1 night won't kill your kid if they're not in bed by 8. If you're out doing something fun, or they're having a blast, don't just drop everything because they have to get to bed.
This would be 1 of those examples. Your kid(s) will remember something like this for the rest of their lives.
The only reason I"m not taking my 5 year old is because the HCBW won't let me take my kids to the rivalry game . . something about my lack of verbal control and yewts lack of not being complete Deutsche Bankers.
