potato chips

I was walking to class the other day and I was eating a bag of lays baked potato chips at the same time. I was kind of making a show out of it and I was thinking, what if I see someone else eating a bag of chips -- wouldn't the slightest head nod be appropriate? So I'm thinking about this and two girls walk past me going the opposite direction. The one farthest away looks straight at me and says: nice bag. She was eating a bag of the same potato chips. I said, hey, you too! It kind of made my afternoon.
