Exactly this is what I am struggling with, while I agree with a quick hello in a place like the supermarket (which I have found is usually the example that most Therapists give) I think that there are other places where a more detailed conversation might be appropriate (and this is just my own personal opinion).

I tried to talk about this with my mom but she kept yelling at me saying that I was obsessing over something that is unlikely to happen (but at the same time knows that I sometimes do that because of my condition) so I decided to go on here and ask the question.
