that really depends on the school/bully. i had one in HS who was convinced he could kick my ass. he was very very wrong. he was sent to the hospital with broken bones. got suspended for a week+ because he swung a stool at me as a weapon. i got suspended for 1 day (only because i technically hit him first) and was unharmed.
he (and anyone else) never bullied me again
You swung first, sent him to the hospital with broken bones (plural) and you were only suspended for a day? I'm not saying that your story isn't true but it is a little hard to believe.
