I should also say I'm fine with travelling, but I only truly like it when I do it by myself. Otherwise the people I'm with annoy the crap out of me. I've only really done travelling by myself once, which was a few years ago when I went to the UK by myself, which I wanted to do because since I moved away many years ago I had only been back for a few hours at a time, usually while waiting for a connecting flight. It was great because I was able to see everything I wanted to see without any annoying people slowing me down with their snail-pace walking and saying "let me get 50 pictures of you standing in front of that building" or "let's go to this stupid shop and look at clothes for 3 hours". I'm very efficient when seeing sights - I just speed-walk from place to place, take my pictures, look at the things and drink them in, then move on to the next thing.
Also when I go places, I only really like sightseeing (which includes taking walks and public transportation rides) and eating, not any human nonsense like going to strange night clubs or strip clubs, socialising with the locals, learning about the local culture through conversations with the locals and hearing their life stories, lying on the beach, etc. In other words, I hate the Anthony Bourdain type of travelling. I never liked that guy's show because he was all about having boring conversations with people, not enough walking around and seeing things. (I guess that's another common thing that I don't relate to - everyone seemed to love Anthony Bourdain while I found him boring.)
I like "sightseeing" in my own city too, and I go walking and biking all over the city to the ravines and other places, and I obviously go by myself. It feels like travelling even though I'm not even leaving the city. If I had to do it with someone else, it would be annoying, and they would object to me going through rough terrain and messy woods and all that. And that time I got trapped in a cemetery
.... that would have been a nightmare if I had someone with me.
