I was at the same YE event as Jeremy on Saturday. Our chapter does a YE event every month. We flew 42 kids this weekend, and working ground crew I'd say I probably saw about a fourth of them after their flights. While I wasn't really keeping track of the kids' expressions (I'm excited enough myself to be around the airplanes)
, looking back, I think I would probably have to guess that probably about half of them didn't show any real excitement.
Yes, some kids show it more than others, but as an example, there is one kid that flew his 11th YE flight on Saturday, and the pilot who was flying him and another kid (the two kids didn't know each other), asked who wanted to sit in the front, and neither answered. Then he asked where they wanted to go - Lake Lanier or Stone Mountain. The one who had flown before answered, so the pilot said the other would sit in front. He asked the kid who had flown before if that was ok, and the kid just said yes.
To me, maybe the kid was just shy - I don't know. I've seen him before, and I think he was more excited the last time, so it could be shyness, but I have to wonder, just in case it isn't, (again, I could be wrong), but if he's not all that interested, why has Dad brought him 11 times? Hard to say, and I'm not trying to say whether he's interested or not, but it does make me wonder.
