Wife wants to give up 8 day trip to Europe for 8th grade promotion

My wife is an amazing mom and her kids always come first. But that creates unforeseen consequences.We had managed to find a round trip ticket to Germany for the 4 of us for than $550 round trip, $2200 total which is a killer deal.The thing was we had to leave the last day of school, but it was only a 1/2 day so we didn't think there was a problem. Now we found out that the 8th grade promotion ceremony is that day, and to change the flights will cost more than $8000. Now she wants to give up the trip to Europe so our son can have his ceremony since he might be getting some awards as he is probably in the top 5 of his class.I don't understand how 90 minutes in a gym with his name getting called a couple of times can be anywhere near as memorable or rewarding as a week in Europe. He told her he wanted to be at the awards (he's kind of a homebody and was lukewarm on the trip).She wants to make sure he's recognized for his hard work, I want him to have memories of something fantastic. Any suggestions? via /r/Parenting https://ift.tt/2GDg7Sl
