A smile is like a disease (But a good one). When someone smile
to others, it will make her/his day. It’s also an answer to a problem when
someone being rude to you. It will automatically make the person feels ashamed
for her/himselves. I’m not usually smiling to others and I don’t smile when
taking pictures. Some people labeled me as a weirdo. But hey, that’s me! Yet,
when someone smiles to me, I will always make sure I smile to that person back
even my day isn’t so good. It's called common courtesy and she/he has made my
day, so why I should not do the same as what he/she did to me, right? So, next
time if you see someone smiles at you even that person is a stranger or you’ve
a bad day, don’t forget to reply it back. You will never know how much the
price of your smile to others.
