19 years old?!

I'm a butcher and have been working at this place for a couple months now. It's a super tiny locally ran place with a small crew. They're all awesome and we get along great. I'm the second oldest at 28 working the knife. Our youngest is 23. I've given the 23 year old crap sometimes for being so young before.

Well last week, all of us were talking while I was busy cutting. I was told by the oldest to be careful and not cut myself. We were all in a sassy mood so I turned to him and said "I've been handling a knife for over 15 years, I got this!" I saw his face glaze over with confusion and he just says "how old are you?!" So I tell him "I'm damn near almost 29!" His reply was "29?! Shit I thought you were 19! I was wondering why you were 4 with a knife!"
