Most days, I go to the gym with my friend Dan. We work out together so that we can spot and encourage each other, but also because we don't always know what to do. So picking exercises becomes a bit collaborative.

At the end of the workout, Dan always wants to do some ab exercises, which I have no desire to do. I feel pretty comfortable with my core, and I don't think I need them, plus I get pretty tired at the end of the workout.

Many days, Dan tells me "let's go do abs" and I tell him I'm going home. "*you* can do abs, I'll see you tomorrow" and we repeat this exchange 3-4 times most days. He 's trying to goad me into staying, but I usually just shower and bail. Am I an asshole? is that a dick move? I haven't had a regular gym-friend in the past, so I don't know if this is against etiquette.
