Not a creepy I-watch-you-sleep-at-night smile, but at genuine one, like they really care about you.
I think that's amazing.
I was having a really bad day today.
And as I was walking home, the mailman waved and said hi to me.
That simple little thing made me so happy and gave me the courage to continue on with a positive attitude.
So now, whenever I can, I'm going to smile at strangers.
In an attempt to brighten their day too.
