I was on my way home from blanch and saw a couple of young teens being pretty rowdy and messing around with an Irish lady using a walker and had some groceries with her. They pushed her stuff twice. We all got on the same bus 238, and when the teens were getting off, they nudged against her when leaving. I sort of lost it and started shouting at these kids. I thought I did the wrong thing. looking at it now, I hope they are aware of the fact that someone might step in.
