I have read and commented on several threads while I've been on mumsnet. I've noticed so many people (including myself - it's easy to be assertive on an anonymous Internet forum) need to learn how to be assertive.
I've developed the cutting glass tinkling laugh to sarcastically laugh of certain comments (maybe PA but it works for me with certain people).
I don't like the "did you mean to be so rude?" Line because if someone says yes I'm stuffed!
What assertiveness techniques do you use?
NO MORE DOORMATS!
