That’s thing maybe happen 1 year ago. I was on the subway, there are so many people on the subway and I ‘m so tired , when I finally found a seat I was glad so I quick sit down . It’s too comfortable when I was tired and I can sit down to relax my leg, my body. I was looking around and I found a squatter, it was a young boy, he looks not good ,he be green around the gills and with two hands pressing his stomach. his mom was very worry talk to someone on phone. I heard she talk the hospital so I think maybe that boy was sick so I let the boy sit my seat. I hope he can be better.
