Our neighbours 12 children rendered our garden unusable over the summer by throwing stuff over the fence, screaming from 7am to 8pm, yelling for us to come talk to them etc. One of them also broke a section of fence - I caught him doing it, and know it was deliberate because he was giggling and told me I couldn't stop him. Fortunately he complied when I ordered him off the fence but we still had to replace that section. (No, his parents did not offer to contribute).
The same child has twice now knocked on the door, rung the doorbell and tried the handle - it opened today because I had just done the bins and he let himself in. I firmly told him to leave (didn't raise my voice) and he did, giggling again.
I don't have kids - is this normal for a 6-7 year old? I'm concerned I'm feeling more annoyed than I should. Am I just being grumpy and AIBU for thinking this is unacceptable behaviour?
