don't promote self esteem or prettyness. noooo not that ahhhhhhh! cover your eyes Children!
Its one thing to tell everyone that they're pretty, and another to ask people to single themselves out. Those who generally don't feel that way won't get any benefit from people asking them if they think they're pretty - in their heads or hearts it's likely to be a : "No, and thanks for making me think it's important, if I didn't have to struggle with that enough as it is"
