Don't generalize from a sample of one. You should pay attention to interactions on a moment to moment basis and keep track of outcomes. If you do find that people start to glaze over when you start talking about alien abductions, you might hypothesize that "delusional and gullible" is something that multiple people would agree to (or, alternatively, that it is boring subject, which is also useful information). If people seem surprised when you express annoyance, this may indicate that they would agree that you are temperamental. If you don't see this when interacting with other people, it is possible that it is your old friend who is actually temperamental and delusional.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
