Have agreed to go away next year for 5 days with a very close friend. She has now asked if someone else can come along as well.
I'm in my 30s and much as I enjoy going on holiday with certain close friends whose interests align with mine, I know myself well enough that I will dread having to go on holiday with someone I don't know well (even if we do meet beforehand). Also 3 is a really awkward number - usually splits into 2 and 1. I just don't really want to spend my holiday making small talk.
AIBU? She knows me pretty well (she has asked if it is ok if someone else comes along) and I'm really not misanthropic but experience has taught me you need to be pretty careful who you go on holiday with!
How do I tell her politely/tactfully (I am a big people pleaser and dislike confrontation) without seeming odd or unsociable (is that even possible?)?
