So Annoyed

My son lost the third and fourth items I know of today. A shirt I bought him within the last month and a pair of pants. He left them at his friends' house. The little kid he got caught taking something from Wal-Mart with. Go over there to get them back and they say he didn't leave anything there. I don't get why my son needs to be around kids that obviously could care less about him. I've tried to teach my kids what a real friend is, but they'd rather let fake friends abuse them.
My son lost a bike that I bought him for his birthday last year by leaving it with a supposed friend. He lost a Freddy Fazbear shirt that was bought for him for Christmas 2016, and now an Avenger's t-shirt. All the nicer stuff I could get him, he loses. I can't afford much, so would hope he would take care of the few good items I could get. There are five children, so it's hard to give them nicer things. 

That need for social acceptance that is rare. Especially for anyone with a mental condition of any kind. People don't seem to accept each other as is. People (children included) have this need to change others to their way or abuse them. It's tiring, I almost can't wait to find out if there is an apocalypse. We as a species definitely would be deserving of it.

Update 6:05 PM: Our other son brought home the items mentioned today. When I asked where he got them, he said it was from the friends' house.

Update 6/28/2016 1724 PM Apparently this situation is going to keep escalating. My fiance told the little boy my son couldn't play with him anymore because of this (we felt flat out lied to) on the day after it happened. Today, their father has his daughter and some other weird woman stop at our house to tell us our other boy is doing something wrong. Based on the weird one's attitude, it seems like it's just to start problems. I don't bother other people here and wish they'd stay away from my door.
