This ones a bit of a slow burner, but it's well worth it.
There is a couple, mm famous for what they do, been on the telly (relevant, not a brag lol!).
We are often at the same events and knew one another before they were remotely famous..
I fell out spectacularly with her, I'd always had a suspicion she didn't like me and so I had always been SUPER nice to her because thats definitely the best thing to do.. hehehe.
Then something kicked off and she was privately UTTERLY vile to me and I was instructed to never speak to or mention them again (oh dear)... and ignore them in public.
However, HE has no idea about the above, and can't help himself in the overly friendly huggy greetings stakes... so EVERY time I see them he says hi and I say hi and we are dramatically effusively friendly...... whilst she FUMES and seeeeethes and can't say a bloody word because its always somewhere VERY public (press offices, near live broadcasts and cameras etc)...
Hahahaha. If looks could kill I'd be 6 feet under.
Otherwise.. if my sister is annoying me and we are out, I will very loudly do either Lou and Andy from Little Britain, or Timmeh from southpark. Both of which make people stare which makes her cringe to the point of physical pain. (Which one I do depends on which wheelchair I am in obviously!)
