I had a stupid confrontation in the park earlier. Another child hurt my son, who called other child stupid. Other child’s mum came storming over and called DS horrible, so I made him apologise, but she continued ranting so I pointed out that her child had hurt mine. She denied it, said they were only playing, and stormed off. Silly, minor stuff, probably caused by everyone being a bit fed up and tense in current circumstances, but I can’t stop going over it in my head. I feel so frustrated by the lack of resolution. And I know I will be all night! Why can’t my brain leave things like this behind? How do I stop dwelling on things that I can’t change?
