Went for lunch with two friends, our children were playing in the play area after lunch. We started making moves to leave (each in our own cars) but then my young child wanted to keep playing so I decided to stay and let him play longer. I called to my two friends that we were staying, shouted bye, my child shouted and asked me why they weren’t answering, and then I shouted again. When I started calling to them they were only two metres away. They kept walking and talking between themselves. I sat down. They walked all the way to their cars. Aibu to feel upset by this? Not sure if I’m being overly sensitive. One friend did then walk back over to say that they had thought I was following.
