The Smile You Aim at the Floor

Open your camera roll and find the photographs of yourself you actually like.

Count how many have your chin tipped down, your head turned a few degrees off centre, and your eyes not quite meeting the lens.

Most women find it is a lot of them.

What the movement is made of

It is not one gesture but a small cluster that tends to travel together.

The chin comes down. The head turns slightly to one side, so the face is presented at an angle rather than square on. The smile is partial, either held back at the corners or lopsided, as though it is escaping rather than being offered. The gaze goes either down and away entirely, or up through the lashes from the lowered head, which is the version everyone recognises from a hundred film posters.

Sometimes a hand joins in near the mouth or the collarbone. Sometimes one shoulder lifts a little. Neither is required.

The whole thing takes about a second and, done genuinely, it is not planned in any part.

Why it does what it does

The reason this expression is so potent is that it contains two contradictory messages running at once.

The smile approaches. The turn withdraws. You are simultaneously giving something and taking a small step back with it, and the result is that the other person is left holding an invitation that has not quite been handed over.

That gap is the entire mechanism. A full, square, unhesitating smile completes itself. Nothing is left to do. A smile aimed at the floor leaves something unfinished, and people move toward unfinished things.

It is also a smile that has been made smaller, and smaller reads as less threatening, more private, more like something that slipped out than something that was decided. Which is why it reads as intimate even when it is aimed across a room.

Where you learned it

Partly nowhere. Small children do a version of it, hiding a delighted face against a parent's leg and then peeking, long before anyone teaches them anything about being charming. Pleasure plus self-consciousness seems to produce this shape on its own.

And partly, if we are honest, from everywhere. Girls are taught, mostly without a single explicit instruction, that taking up less room is safer and more likeable. Lower your chin, soften it, do not be too much. A gesture that starts as spontaneous delight gets reinforced every time it is rewarded, until it becomes a reflex that fires whether or not there is any delight involved.

Both of these are true at the same time, which is why this particular expression is so hard to think about clearly.

The uncomfortable part

Here is the thing nobody mentions when they describe this as a flirtation signal.

The same movement, muscle for muscle, appears when a woman is praised in a meeting and does not know where to put herself. When she is being looked at and would rather not be. When she is apologising for something that was not her fault. When she is making herself small in a room where she has decided that is the wise thing to do.

From the outside these are close to identical. From the inside they could not be more different: one is pleasure with a bit of shyness attached, the other is discomfort with a smile stuck on top of it because a smile is the socially required response.

You are the only person who knows which one you just did. Which is worth knowing, because it means two things at once. Nobody can read your inner state from it, so you can relax about being transparent. And nobody can read your inner state from it, so if you are doing the shrinking version, it will very often be received as the flirtatious one.

Doing it on purpose

In photographs it genuinely works, and there is no reason to be precious about that. The chin-down angle shortens the face slightly, defines the jaw, and the off-centre turn gives depth that a straight-on shot does not have. The half-smile photographs better than a held full smile, which after two seconds starts to look like it hurts.

One honest caveat, though. A face that is fully committed to what it is doing is very often more compelling than a face that is hedging, and the coy angle is hedging by design. Every portrait in the same pose starts to read as a woman who is never quite present. Mix it up. Some of the best photographs of anyone are the ones where they are looking straight down the lens, entirely unguarded, having a completely uncoy time.

Doing it less, if you want to

If you have noticed yourself doing the shrinking version, the instruction is smaller than you think and harder than it sounds.

When someone says something good about you, keep your chin level. Let the smile go all the way. Say thank you, and then say nothing else, particularly not a joke at your own expense.

That is it. It will feel enormous and faintly rude the first few times, in the way that all recalibration does. It is not rude. It is simply what it feels like to receive something without immediately handing back change.

Practise it on someone who is safe. Then take it into rooms that are not.
