I would give a donation to a zoo(because that's where they really belong) in their names. Or donate to some organization in the little monster's names that helps kids who would not be ungrateful, hey, someone has to teach them about empathy and humility, doesn't look like their parents are.
I gotta slime for a minute about my brother's kids. My niece and nephew. It's horrible that I say this about family but they're brats. He has twins: one boy, one girl 6 years old.
The girl always gets her way as long as she cries about things and the boy is a bully who, the last time we got together, kicked my son in the back and gave him a giant gash.
Now comes the annual Christmas exchange. What to get them? They have everything and never say thank you for what they get.
I really don't want to buy them toys. Books? Magazines? Clothes?
What do you think?
Looks like I am in the minority but I would just purchase them a gift I think they would enjoy, give them a hug and wish them a Merry Christmas. They are your neice and nephew and I would try and love them just because of that.
Issues regarding behavior and how they treat your son can be dealt with separately, as they happen and with your brother and sister in law.
IMHO the holidays are for enjoying family and friends and all the small stuff can take a backseat for a few days.
