Ha ha- that's a great question. I definitely think heaven could end up being hell for me. After a brief, friendly reunion with my family, if they are the same they were on earth (which I'm guessing is kind of the point,) some of them would no doubt start to show their disappointment with me and nag me. Plus- what on earth are you supposed to do forever? And, any realm created by the God who created this earth, I'd have severe doubts about.
On the other hand, I'm maybe not quite deviant enough to enjoy hell. I have some darker elements to me but, probably not quite enough to enjoy everything that would be going on down there!
