ok back story is
DS1 has a fb page and a "friend" has repeatedly called him a "Retard" a term I hate.
I left a message on his status which said
DS1 you need to look at who you are friends with if this is what they see as an acceptable way to speak to people.
DS1 deleted my comment today whilst at my mums.
I reposted it and he deleted it again.
I spoke to him in fb chat and he got really cocky so I called him.
I explained to him that it is not a "joke" to be called a retard and it is actually offensive.
He then started talking down to me, all the time my mum was sitting there (he is staying with her) and not once did she say a word to him, I told him I would close his account if he didn't apologise and stop yet he carried on.
AIBU to think my mum whose care he is in should have said "Stop being rude"
and I know she was in the room as when I asked what time he would be home he asked her
