Do spoilsports/wet blankets/party poopers enjoy what they do or are they just miserable people?

I'd say they are miserable. What the hell are they doing at a party?

Probably some of both.

Well sure they enjoy it That's why they're all one big pack of miserable whiners. 

 

(Comma after the second use of the word “do”.)
(I also wonder whether or not this is yet another instance of willful intent to bait an officer. Grrrrrrr.)

I've know people who poop at parties.  :  (

This might surprize you but I have been called a party pooper a few times because I had to shut a out of control party down or cut people off. But I didn't enjoy doing it. I have also been called a Mother Hen a few times because I made sure people put their jacket on before they went outside to get in a puff puff pass circle. Cheers and Happy New Year!

I think those who need to bring down others in an attempt to feel better about themselves are definitely in some sort of misery. I feel sadness and compassion for them, amidst the anger and annoyance.
