I punched some older lady in the arm since she kept hitting me with her trolley
How cruel is that? Is there another reason you punched her?
Actually I hate old women, they behave like they're on their last years on earth and they drive like cowards on the roads
It can be upsetting to get hit but you shouldn't hit people anyways. You could cause serious damage to somebody and get in trouble. It would be better to walk away.
My arms are pretty powerful and I hate this WW2 generation, they're all grannies on the roads.
Just because they are of another generation, doesn't mean you can do physical harm on them. The older lady might not be very coordinated, so how about being more patient instead of resorting to violence and hate?
