sencerity AND playfulness

ok well when you talk to your crush(or friend that you dont think of as a friend anymore)say his name alot with a kind of genle tone and stare into his eyes the whole time you are speaking to him. Then look at your hand suddenly turn this way and that , he,ll probably say,"whats wrong?" the ask him if you can see his hand. If he says yes then take it and line it up perfectly and then say,"aww man! my hand is so small/big compared to yours!" ususally that gets them to smile or laugh with you or to hug you saying, "well your hands are nice that way"
