I was waiting at the checkout counter when a mother and her handicapped child walk up behind me. I didn't really care at all until the child keeps poking me and tugging at my shirt. I turned around to see this "child" was probably a teenager about 14 years old. . I asked multiple times for him to stop; gradually getting more and more irritated. Eventually he grabbed my shirt once more so I turned around and said "listen here retard. Touch me again and ill fucking break your hand off okay?" The kid started crying and I have absolutely no regrets about what I did.
