bullies

I went running just now and on the way i passed by a group of kids. From afar i saw one big chubby Chinese boy and 3 other smaller kids. when I got closer I noticed that the 3 littler ones, had their arms linked and was pushing the chubby Chinese boy.
And for some reason I started worrying for the chubby one, wondering if I should stop the bullying. But then I figured the chubby boy must've bullied the little ones in the past and they're all now standing up to him in a group. *shrug*
