Poor lady... How disrespectful.
From my experience, (some) American kids in particular are so rude. I was in New York in October, and on our last day these 3 kids came over to the bench where we sat at a subway stop and started bullying this asian lady next to us. At first they took her umbrella and said some nasty things to her then they started taunting her and making her uncomfortable by asking all these rude questions. It wasn't until I physically took the umbrella away from them that they backed off...on her. Then they started doing the same **** to us, but I wasn't having it and after arguing with them for about a minute the train got there and they got on a different line.
I have never experienced anything like that with kids anywhere else, and I've been in a lot of different places of the world. I don't know if it's a cultural thing or just random but it was shocking to me. They weren't the only shitkids I saw there but it was my only direct encounter. I wonder what their parents are doing
