Recently got a teacher assistant position at my university, helping my old professor with his class. Told my gf and she asks if I’m going to help the females in the class (of course I am it’s my fucking job).

I just laughed and said of course not, why would I do that? I’m only here to help myself.

Looking back im not sure if I said the right thing. How do you reply when they ask how you’ll conduct yourself around other females?
