I have a really hard time improvising dialogue and making on-the-spot decisions. Usually the moment something doesn't go the way I expect it to, I can't think of anything to replace it. And my GM says we break his campaign in significant ways all the time, and he is able to just wrap around and make something new of it. When my character talks to a NPC, he responds instantly every time. Even Sendings, with having to count words, he rarely takes more than a few seconds. I am in awe, and I think he might be an actual wizard. But that is not anything I feel I am able to do.
