It's summer here in Australia, so my kids (14M, 17M, and 19M) have been having their friends over quite frequently, in particular to swim in our pool. Pretty much every evening, there is someone over.
The other day, I was putting the trash out around the side of the house, when I spotted one of my son's friends looking a bit lost. I asked what was the matter, and he said "Oh, I'm just looking for a place to pee". I told him where the bathroom was, to which he replied "Don't worry, I'm happy to just go here". He waited for me to leave and then I presume he peed in the bushes around the side.
I asked one of my sons about it, and he said that everyone just goes in the bushes around the backyard. I told him, "you know we have three bathrooms, right, and everyone's welcome to use them", to which he said it was fine.
I'm not an avid gardener so don't really care too much about the plants, but I just think its a bit gross to have heaps of boys peeing in those bushes every day. Am I being unreasonable? Am I overreacting?
