Wow. I wonder where you live that people just kept on walking and didn’t even call the ambulance or asked if he is ok. It’s quite bizarre honestly. One thing not physically helping him to get up out of fear of harming him. Another thing is just completely ignore it.

I lived on two continents and travelled to many US states and to many countries and have never seen a situation when a person fell down in front of crowds of people and no one even said anything. That’s just some asinine behaviors. Is it common where you live? It’s not common behavior in my observation at all. Bizarre to say the least
