She knows it won't bankrupt us - she knows our finances every bit as well as I do. But people who lived through hardship see money a lot differently. Speak to folks who lived through the great depression. My grand-parents died and had money hidden all through their house. They didn't trust the banks because of what happened, and died sitting on a huge (8 figures) chunk of money because they were (irrationally?) afraid of something similar happening again.
Anyway - the hammer fell today. She decided we shouldn't go. (Can I call it or what?) So I proposed that we spend the 4 days touring all the local lock-up room scenarios (there are dozens). In the evenings we'll do a couple wine-tasting tours without the rug rats. We can do a ton of them for almost nothing. She jumped right on it and has them scheduled. We'll hit a local waterpark too.
Ah well. Such is life.
