Hmm, sounds like a tough road ahead for me, I don't have a simple answer to any of these.
1) Do I like horror movies? - It depends, it has to have a point, can't be just a gore fest, and my appreciation declines sharply with harm to animals.
2) Have you ever traveled around another country alone? - How alone are we talking? I've gone to other countries of my own volition and traveled around within them, but there is always some pre-existing organization at the core, and I've never had great difficulty finding others in country to tag along for a journey.
3)Wouldn't it be fun to chuck it all and go live on a sailboat? - In theory, yes, it would be quite fun. The idea is romantic, and I yearn for a more minimalist lifestyle. On the other hand, I know people who have done it, and realize it's not all its cracked up to be. You can only be rootless for so long, and it's an expensive way to live. Would I try it myself? I wouldn't rule it out, but at this point in my life it wouldn't work.
My SO can be a pain in the ass answering questions too, so maybe we are a match.
