Good forward mikey. 
I try to smile at everybody too, just makes for a better day. I remember one time I was walking into a corner drug store in a pretty rough nieghborhood in chicago, and this really big dude with like full sleeve tattoos (and even a neck tat too as I remember!), was coming out, so I held the door for him and just kinda gave him a smile. He looked at me and said "What the **** are you smiling at?", and all I could say was "**** man, I just smile at everybody.", and he was all apologetic after that, but I was thinking for a second, I can't believe I'm gonna get in a fight 'cause of a smile?! 
I try to look less goofy when smiling now though.
A good song for the smile thread (starts slow, gets better).
