Smiling at other people

Hey guys, wanted to tell you whats kind of power a smile has. Imagine you're having a really bad day and someone you dont know personally smiles at you and makes you feel kinda better. Some people just dont know how beautiful their smile is. So guys next time when you're outside meeting others People you dont know try to smile at them. Maybe they'll smile back :) a smiling always makes other People feel comfortable. Have a nice day!
