Heaven and Hell

So Heaven's this huuuuuge party, with lots of booze, food and live bands (or dead bands for that matter) with shitloads of interesting people to talk to and fun stuff to do - and you can stay as long as you like, chill out if you want, whatever.

And Hell is: You're not invited (Cos you're an arsehole)

I've reworked the above text many times over the years, but upon reflection, the shorter succinct version is the best for me. The basic changes I wanted to make were to say:
If you've ever chucked a big party with a big mix of friends, you've probably encountered people who don't seem to get on well with others. One on one they're cool people, but in groups or when boozing they do things that upset or annoy others, time after time. So while you care about them and would like them to come to your party, you know that it would spoil it for others, so you have to leave them off of the invite list...
