Idiotic things I did this week

Running on two hours of sleep, I introduced myself to my new manager using his name. "Hi, I'm Nick," I said, shaking his hand.

I believe this is the worst first impression I have ever made.

Later that same day, I let one of my co-workers cut my hair. I've got a few grey hairs near my part, and I thought he was kidding when he came towards me with the scissors. He wasn't kidding, but he did miss the grey hairs entirely.
