On facebook...
I said, "today was hilarious. i was at a loss of words from your cute crooked smile, hope it doesn't come out in the portrait

"
She said,
"ahahha yeah just a little akward. I do that girl smile all the time."
I don't trust myself as to how to respond to that anymore. I need to get a good idea of how I can respond because I always end up with weak responses that make me sound dumb.
Here are examples of how I would respond and you'll see how dumb the responses are:
"oh hehe...i bet it was only a preview" (as in she has more cute imperfect things about her besides the crooked smile)
"oh lol, i noticed a lot of girls do that" (to make her feel "unspecial," to be like everyone else)
