You often give a smile to your friends but sometimes that smile is forced to be on your face you act like something's wrong when something is wrong, your friends ask if your okay the only thing you say to them is " I'm fine " . so your friends don't question it but only true friends know when something's wrong when you say " I'm fine " so they try everything to make you feel better. And when they do a true smile comes upon your  face.

Again I did not mean to offend anyone just try to see the best of your self, not the bad part and if your days bad then just talk to your best friend or your friends and they will try everything to make you feel better
