I'm not close to my neighbour but we speak whenever we see each other.
Today her son (about 16/17) was picking up his brother from school (about 7/8 I think).
They were walking to the bus stop but they were behind me and my DCs. I heard the youngest shouting give me my drink but he kept saying no. He then sat on the floor and then he went over and pulled him up by his arm and was then grabbing him.
We then got on the bus and so did they. I was keeping an eye on my DCs but I heard the youngest keep asking for his drink but the eldest carried on saying no. I then saw the eldest hit the youngest. The youngest then called him evil and he said something like stop being a dickhead then and the youngest then went and sat somewhere else.
Should I tell my neighbour or stay out of it? Wwyd?
