Hmmm, I'm glad someone had a good time. No, actually, I spent it at home but it was an Ok night.
Glad you had fun and glad your friend made you go. But, I am so sorry you now have a hurt knee. I hope there is nothing seriously wrong with it.
No fights? Good job!! Sometimes, parties can get out of hand and glad this one sounds like it was just enjoyable all the way around.
Have a great New Year!!
