Strange nsv

Today I had to pick up my 20 year old at work. I told him I was at Aldi's next door and to walk over there. I saw him come in the door and then I saw him walk right past me....not once but twice! At the end of the aisle he pulled out his phone and called me and said "Where are you?" I told him to turn around. He laughed and said....I didn't recognize you being all skinny!
