I think your kids are annoying
Why do you think my kids are annoying?
they don't listen to me and my goal is to have a quiet house.
Even if the kids don't listen to you, it's not okay to tell someone that the kids are annoying. They might feel like you're attacking their parenting skills if you question their ability to keep their kids quiet. Try to find a place you can be alone and have privacy in your house instead when the kids come over.
I just want some time to myself. I have enough space to go private and no kids around me.
I'm sorry that my kids are being a little noisy. I'll try to get them to quiet down when needed. Do you think the kids would feel comfortable around you if you said such things around them? Simply try to tell them politely that you need to be alone if it comes to that.
