Why hate on people when you can always show love?
First of all, to all of us lazy people out there, it's so much more effort to hate when you can give someone a hug or tell them they're rocking their outfit.
It never hurts to ask someone how their day was or even just shoot them a smile. It can always make their day because you don't know what they're going through. Maybe their horrible day has turned into an "ok" day because of something small you might've said.
Most importantly, if you were having a bad day, wouldn't you like something to cheer yourself up?
So, instead of wasting tine hating on people, give out more hugs, ask someone how their day was, anything that could cheer someone up. It's never to late to make some friends.
