PMSL, that's very funny!
There're loads of things I do that I told myself I wouldn't The most recent one was me telling Natty "not today, darling". I still remember getting sooooo cross when my mum said that to me when I asked for something. Well if not today, when? But I know I must have said it a fair bit because Natty has started repeating it. *Sigh* Fail. LOL!
