I used to call people and then they would pick up and be like "this is ___ speaking, how can I help you" and then I would just draw a blank. Mind empty. It's SO helpful to just write down a few lines to fall back on because otherwise I word vomit and It's hard for the person on the other end to understand what I want since instead of going "1,2,3,4" I say "4 because 1, well actually hang on 3 and now I am going to tangent on 2...."
I think phone call are hard for me because I can't see the person's face, so it also helps to imagine their face.
I think Dance Dance revolution comes to mind for me because when you fuck up in the rythem and then have to brute force your way through until the song ends.
