I Can't Stop Smiling lyrics

I can't stop smiling and i don't know why I want to anyway
So many times before i could hardly even force one to my face
I'll trade you a smile for a shake
I know that's something you just can't fake
It could mean nothing
It could mean nothing, it could mean everything
When you started playing rough
Fit you like a boxing glove
Can't stop smiling long enough to say
I can't stop smiling long enough to pretend to sympathize
Only months ago you would never even take the time to write
(I can't figure this line out for the life of me. Help Craig!)
I'm not listening anyway
So tell me something
So tell me something, I can do anything
Show me that i'm wrong enough
Need to know that kind of stuff
Can't stop smiling long enough today
