Size of My Crack

Isn't it interesting when you find out something about yourself that means absolutely nothin.  But still funny.
We were at my mom's house and Mom asked whose can of soda was on the kitchen counter-- Will picked it up, glanced at the top and matter of factly said-- "It is Cassandra's."

Huh?  How did he know?  I looked at it--and no lipstick was on it, so how?

Then he showed me something he has known for over a year that I did not.  I am a lazy-ass can opener.

Evidently, when I open a soda can, I barely crack it open and don't fully push the tab back-- and Will rams the thing all the way back. 
He's the soda yin to my can yang.
