One of my coworkers moved to another state, and now lives only about 30 minutes from his in-laws. When they moved out of their house here, they did a very mustachian thing: Anything that didn't fit in the 28-foot trailer wouldn't go, and would have to be thrown out or sold or donated.
So far so good. They got rid of a ton of clutter, their new house is staying clean-ish, and they're only unpacking boxes as they need the contents. Having just moved less than two weeks before Christmas, coworker and his wife kept their family's gift-giving to a fairly reasonable 2-3 gifts per child. All was well--the kids unwrapped their present and played happily on Christmas morning.
Unfortunately, coworker's MIL (hereafter referred to as Grandma) has a love language of gift giving, and is VERY excited to have coworker's family nearby after 16 years of living a long way away. So coworker and his family trekked over to Grandma's house for Round 2 of gift opening. Now, I would be remiss if I didn't add that coworker's wife has two sisters, each married with their own kids, and all were invited to Grandma's house. Grandma, being so excited to have coworker's family close again, went hog-wild with the gifts. Round 2 turned into Round 3, and then Round 4, and then Round 5. As my coworker described it, the kids were positively sick of opening gifts halfway through. I asked coworker what kinds of gifts Grandma got him. He said "a big bin's worth of crap. It's as if she walked through Walmart and just pulled stuff off the shelf as it caught her eye."
Now, Grandma is a dear, sweet soul. She's gracious, loving, and a wonderful mom. I really feel for my coworker, though. He and his wife put forth a ton of effort to declutter their old house in order to give themselves a chance to reduce the clutter in their new house.
