A lot of things I'd assume. I'd regret not being able to learn most of the European languages and along with that, not being able to travel across Europe and other places of interest. I'm also quite happy right now and am close to several people, it'd be a shame to leave them behind. I also feel that I should make amends with a few people, a lot of things that weren't said, especially my dad. We don't have the best relationship and I think leaving him on bad terms would be upsetting.
