Spit

I was standing in the queue for the Q28 bus in Flushing and was waiting by a group of High School kids also waiting. There were about six of them, and they all took turns spitting about every 15 seconds. It was repulsive. What is wrong with an entire bunch of kids that they need to clam so often? If this behavior were an aberration it might not be so bad, but this happens regularly. Girls. Boys. All standing around in groups spitting. What the phuc is going on???
