My girlfriend asked me this morning where I was off to? I said- To deposit a check. From who? From my last gig. You get paid to do that? Yes. Her- Whodathunkit?
I think the problem here may be that your friend is an idiot. Edit: I’m assuming it’s a platonic girlfriend. Otherwise I’m sure she’s lovely and brilliant.
Next time she pops an ignorant question like that take her on a gig , have her load the car, set up gear, sound check it, play, tear down, load up again take it home, unload again.
To be fair, if you point to a bit of ground and tell me that's home tonight - you'll be surprised at how quickly I'll fall asleep. So I suppose in that regard we sleep around.
Based on some bits and pieces of your career I have picked up on from some of your posts, I'm guessing she hasn't known you all thag long.
