I am a white dude with Mexican in-laws. It took me a while to adapt to the concept of Mexican time. For years, we would show up to events at the time on the invitation and would be the only guests there for hours. By the time we were ready to leave, most other guests would just be arriving. We finally got used to it and most recently went to a birthday party for an 8 year old that said it was starting at 2:00PM. We got there around 6:00 and it was perfect timing.

With that being said, I still can't hang with the Mexican ending times. They'll keep a little kid's birthday party in full on rager mode until like 3 in the morning.
