Dork is the technical term for a whale's penis, so I can understand that one.

DS is allowed to say whatever I say: makes me watch my language! He sometimes comes home with the odd word/phrase from nursery I don't like (eg go away or shut up) and I tell him that's not nice. It's OK to ask for alone time and it's OK to ask someone to be quiet, so I have to work hard on modelling that (and not just screaming at DH and DS "stop touching me! Stop it! Further away! Go outside! I can't cope!" as I did last month).
