I'm tempted to say Japan, but I know it won't be half as amazing as I think it is in my head. I've hardly seen anything of the country, so I'll say Australia or Canada. My brother told me Europe is nice as well though, so I can't say anything definite.
I know I don't like England, it's just boring. Everything looks the same, people are disgusting (as in, hands down their pants spitting on every slab in the pavement disgusting), the weather is depressing and even the "best" parts of the country are boring. I wanna go to the fucking beach in my free time, or play basketball on an open court, or (if in Canada) go skiing. I imagine other countries have their problems too (if not these precise problems) but I don't know enough to say either way.
