Exactly. Of course they're going to ACT like they like the gift. But in the back of their minds they're probably thinking, "and WHY should I care about this vacation I didn't go on??"
If my parents went on a fabulous cruise without me (which they do ALL THE TIME), and then for Christmas handed me a gift of their personal memories and pictures of the cruise, I'd be kinda irked! Gee mom, thanks for reminding me how much fun you had without me!
I do enjoy seeing her pics on Facebook, but I don't want them wrapped up with a bow and given to me as a present.
Does that mean I don't love my parents? Of course not. I just don't see how their vacation that I didn't go on is somehow supposed to make me feel good.
There are so many more thoughtful things that could be done.
