I can completely understand where you are coming from. It is frustrating and annoying as hell to rack your brain to come up with ideas for picky people, only to have the items rejected. To also feel obligated to take things when you are the one paying all the money and making the effort to travel (knowing picky people are going to grumble about them anyway) would be enough to make me want to forget the whole idea of taking anything.
I'm the opposite, lucky to have family that isn't picky and appreciates what I bring back. This time, however, with all we have to pack and ship, we aren't going to be able to take anything back. I'm feeling bad about it since we are trying to keep shipping costs down, and not wanting to pay for overweight cases on top of a spare case each. The funny (funny odd, not funny haha) thing is, as much as it is bothering me, I know no one is going to care, because they'd rather have us home than 'stuff'. It is just that my inner Santa loves giving gifts every chance I can get all year.
