Hehhhe... Normally the thread is cruising along at a good clip at that time of evening. I know this as it annoys the heck out of me that I need to leave just as things are picking up.
I usually leave just before things start to get lively. I've stayed and played two night in the last week, and I'm paying for it now. Eleven hours of sleep and I'm still dragging. Remind me not to have so much fun, OK? Or tell me to at least have fun in the daylight...;o]
