When I was around 15, I used to hang out with a guy who was much senior to me, and he would bully us sometimes. One day, when we were bantering, I cracked a joke that a third guy with us (who was my age) found funny and crackled. The bully grabbed my neck and choked me till I lost consciousness. I remember having memory flashbacks related to missing a train, and someone waiting at the wagon door, waving at me to hurry and jump in before it is too late. I remember feeling stressed about missing the train. The next thing I remember is slowly regaining consciousness to see the bully and the 3rd guy splashing water at my face, looking very amused.
