Today at track, I forgot to take off my necklace. Since we are not supposed to wear jewelry, some kid a year younger than me came up to me and angrily said, "Take off your necklace or I'm gonna choke you." Now I was just jogging and minding my own business!! After he lapped me and came up to me again and said, "Got it off yet?" I freaked out and chased him. He laughed and laughed. This was at 4 p.m. today. It's 10:33 p.m. right now. I am still shaken up about it. Any advice, please?
