OP already accounted for social situations where you would expect to meet people, though, and his parents seem to think that he should be approaching people in other situations—like in a store, or on the street. I’d be very cautious about that.

Oh damn, I got the rabies vaccine when I worked part time at a vet school because they offered it. They were like “Uh but you’re IT, you don’t really need it, so you could skip the hassle…” and I was like “Why would I turn down an opportunity to get a vaccine? You’re paying for it, right? Reprogramming my immune system is awesome, sign me up!”

No wonder they looked annoyed, LMAO.
