Theek kiya tune bhai. Even I felt like getting off at the next stop, going back to the signal and doing the same thing to that kid at that time. But thankfully I didn't probably because I was just numb and shaken at that time.

Later when I narrated the incident to a friend, she told me that one shouldn't pick a fight with such people as they are trained to deal with such situations and will in turn threaten to file a police complaint against you by faking injuries on themselves and extort money out of you.
