I have a friend who I've known for years, I've always really liked her. We don't see each other very often these days as she moved further away, but we have similar aged DC's so stay in touch via FB. She's asked me to meet up a few times lately and I've found myself putting it off.
I think the trouble is she seems to be incredibly vain. She takes very posed, very frequent selfie type photographs. I'm talking about 4 or 5 a week. Sometimes she films 'pop video' clips of herself miming or dancing to songs. She's a 34 year old housewife, moderately attractive - but even if she looked like Elle MacPherson I'd find it weird.
I have no idea why this bothers me, but for some reason it make her less appealing to me as a friend.
