Our first day in France (New Year's Eve!), we mentioned that it might take a few days to get adjusted to the time change (6 hours) and Thad responded without hesitation: "I'm adjusted!"
We proceeded to explain that he might be tired before it is time to go to bed and that being adjusted after an international move usually takes a few days or even weeks. He didn't seem convinced.
The next day, we were talking about adjusting again and how it is okay that we are not all completely comfortable in our new place yet. Thad didn't miss a beat and said "I'm comfortable." And what do you say to that?!
