I've never been a morning person. That is my first confession. I have a good time if I get up and join along a party going somewhere early on a Saturday (a trip to the lake), but there is usually a soul searching moment before I agree wondering if I really want to or if it is worth it. In Spain, we meet at 8:30am for a trip to the mountains. Still feels early.
In Spain, things usually start later. Our church started at 11:30 (out at 2pm). The church we went to in language school only had evening church at 6pm. No one ever wants to meet for breakfast because they don't do that and there's no where to go eat breakfast. Events in general don't start exactly on time.
On the other hand, they think nothing of meeting at 9 or 10pm for dinner and then going out after that. I did go to hear my brother play in a band recently leaving the house at 9pm and that didn't cross my mind at all as unusual at all.
I was recently at an American event that started at 8:30am. Someone made the comment about starting on time and getting "up and running" in the morning and how satisfying those two things are.
I recognized that my own personality of late rising and the combo of being in Spain where things aren't started on time generally makes me less and less comfortable with strong punctuality and early meetings. It was a very North American moment. On the other hand, I'm a grown up and know when I'm home I need to get with the US system. It's just funny to find yourself outside your cultural norm.
