An online chat, held moments ago:
Christina: and i had a brownie and a lemon square ...
Me: funny... i had a lemon and a brownie square
Christina: hmmm most people dont eat lemons
Me: well i do. and my mouth hasn't unwound itself from a pucker position since
Me: total strangers think i'm trying to kiss them
Me: and i am, but that's besides the point
