Nippy

A conversation with my 14 yr old son (the one who likes to pose on the roof).

Me: "Brrr...it's a little nippy out here"
Him: "HeHeHe....'nippy' HeHeHe"
Me: snicker, hoping he doesn't see me
Him: ""NIPPY" Hehehehehehehe"
Him: "Oh My God......is THAT why they call it Nippy?"
Me: (laughing hysterically) "Ask your grandpa"
