Input: So, a little background, I don't live at home with my parents, I live abroad but all three of my brothers , 11, 17, 18 years old all still live at home. Even since before I moved out in the mid-end of 2017, my youngest brother's best friend (He's the same age as my youngest brother) has been staying at my parents a lot, every free weekend or holiday (this includes the ENTIRE summer holidays more of less). 

So here's my problem, I don't like that my parents need to spend so much extra money on feeding and housing another kid that isn't even theirs, the kid is nice enough but when I went home for Christmas I found him opening our drawers and going through the snacks we have in the kitchen as if he was at home, this pissed me off a bit, mostly because you don't really do that at someon elses place, right? I couldn't even get a proper family evening without this other kid being there when I was home for 2 weeks over Christmas other than Christmas eve.

His parents also make no effort in paying for him even though they use my parents place as a hotel for their kid. They even go on vacations and just leave their kid with my parents. This boy has 2 older siblings one who's around 25 (give or take) and another who's 20 so they are very capable of taking care of their younger brother when the parents leave for their little vacations.

I also think my brothers, not only the youngest, is starting feel a bit smothered by him constantly being there, the same as my parents.  My nan has also commented on that she thinks he can stay home for a weekend at least. 

This kid joins everywhere, extended family birthday celebrations, family outings, he even joined my parents and youngest brother to watch my two other brother play in a football (soccer if you're American) cup, this trip takes abour 4h to make so they had to sleep at my grandparents who live about 2h away from the city hosting the cup (the games were stretched over about 3-4 days I think) but my parents got train tickets that would get them there and back to my grandparents so they wouldn't have to take the car or bother with parking, meaning they had to pay the kids ticket, too, and to be honest I don't know if his parents paid for these expenses but I honestly doubt they did.

I've talked to my mom about this how it's not her or my dad's responsibility to almost raise this kid but as the nursery teacher she is she can't help but taking care of him, I understand that his home situation might not be ideal but should it be my family's responsibility to take care of him? In my opinion my parents are too kind and giving way for this kind of behaviour.

So am I the ass for thinking he can spend at least an entire weekend at home or for his parents to compensate at least a bit? I get that I'm a bit of an ass, me being an adult thinking like this of an 11 year old kid but genuinely my biggest problem is probably his parents who allow this without a second thought.
