boo-hoo bully

i witnessed a 'bullying' case of a female adult to a 13-year-old boy and all i could do was just watch.

this protective mother scolded the 13-year-old boy in front of all his friends and his boy. in her 'clarifications' (her own words) with the boy, she sounded him for changing his boy's name. she said, "i have given such a lovely name to my son, don't you dare change it. this is my last warning to you." and other stuff like don't you bully my son, blah blah blah.
i couldn't be bothered to listen any more.

i wonder if anyone has ever scolded her son like how she did for teasing? i am sure her son is no angel from what i see. boys will be boys and of course teasing is something unavoidable at this age.
tell me who haven't been teased before? gosh, last time we have nicknames based on colours, numbers, height, weight, animals, things, hairstyle, fruits, etc. and we did not have parents picking fights with our peers...do we??

i personally think the boy who was scolded did not deserve such harsh bombardment in front of all his friends. she could have pulled the boy aside and spoke nicely to him. her son might lose a few friends or one friend now. but on the other hand, children are quite forgiving so maybe what happened yesterday is already the past.
