UPDATE: Entitled mother-in-law invites herself to vacation, family rebook vacation for new spot and leave her fuming: '[Mother-in-law] ended up canceling and had to pay a 50% fee'

There are few encounters more awkward than having to tell someone they aren't invited to an event they were planning on attending. This is especially awkward if the person you've excluded is someone you care about… but you just don't want them around at that particular event. 

For some reason, a lot of parents and in-laws have trouble with boundaries like this. If you find out that your adult child is going on vacation with their own family, and your first instinct is to be upset that they didn't invite you, you should question why you feel that way. After all, there are plenty of other times you can see your child. You could even plan a separate vacation with your grown child and the grandkids, which would help out your kid, since they'd have less planning to juggle. 

But no… a lot of parents get extremely upset if they discover their adult child is vacationing without them. This is just bizarre, because what do you mean you want to tag along on a couple's vacation? Why would you want to insist on going to a trip you're not wanted on? Why does all of this upset you personally when it's really and truly not personal? 

This mother-in-law discovered that her adult son and his wife were going on a trip to a resort, and her first instinct, bizarrely, was to whip out her credit card and try to book herself into a hotel room for the same time and date! Even if she had succeeded in joining her kid, why would she want to endure the awkwardness that would ensue? It's just so odd… check out what happened below, along with the very satisfying update, both included down below.
