This has been annoying me for some time and its certainly inconvenient.
When I returned to the UK 3 years ago, my house and cat were left in the care of DS (single, mid-30s). I pay the major bills and he checks on the mail if there's anything important for me. Shortly after I left he told us he'd run into a friend from high school who was having a hard time: very messy divorce with three young kids and his brother wanting him to move out of his house (both parents dead) So DS offered to put him up while he got sorted out. We thought this was a good thing: company for DS, they could split expenses and someone to mind the house and cat when DS is away. So this guy (we'll call him K) moved in with a large hairy German Shepherd and enough household and sports equipment to set up a separate establishment. K is not paying any rent as such -- just meant to share costs of food and the media contract. The garage is now full of his stuff, including a broken down motorcycle, kids' toys, two or three adult bicycles etc. He had to install all those childproof locks on the cupboards for when he has the kids. The dog has had accidents on the hard wood floors and my mother's rugs. They have put up two baby gates to keep the dog from eating the cat's food. There is dog fur everywhere. When put out in the yard it barks and has escaped several times and I know it's not registered. K will only rarely do the trash run to the dump (which everybody hates I admit) because he has three child seats in his car. He's broken a TV of DS's trying to 'fix' it and has also ripped out the shower stall from the bathroom in our basement! (There was a crack in the pan so I told DS it was better not
to use it until we can replace it -- now I'll have to replace the whole thing) There is no counter space in the kitchen because he has so many boxes of exotic tea and I trip over cartons of food, kids stuff, pots and pans all over -- not to mention the golf clubs, ice skates, roller blades, golf shoes, rock climbing gear...
It used to be somewhat amusing but now I get emailed spews from K all about how DS overspends (true) and eats the wrong food (true) It has been suggested that he clean up or clear out.
End of rant.
