Misunderstanding in facebook!!!!!

I helped my friend to create facebook account and I replied 'I know u r online rite’. Then my friend said 'don be busybody’. This has created a misunderstanding between my sisters and my friend.As the result,he was scolded by them. They said 'do not bully my bro, if not I will whack you' and 'do not bully my bro if not, I will complain to you mother'. This situation makes me laugh for few hours. I cannot believe that my sisters are so concern about me. I feel touch .Hence, my friend blocked me in his facebook account.
