To not want to be friends with someone who's too perfect?

[CarrieMyBag]

Currently I am working with a woman who's so kind, always polite, and sweet. Everybody at work loves her. I do like working with her in professional capacity. Lately she's trying very hard to befriend me by asking me for coffee, lunch, etc. As nice as she is, I have no intention to be friends with her. I am quite frustrated by how polite she is, she's so eager to smile whenever I am about to say something, anything, and she's so eager to help as well. In a word, she's perfect! I feel guilty for not liking her as much as I should have. To be honest, I find her boring. I am more drawn to people who have flaws, funny, and occasionally put their foot in their mouths. I feel guilty whenever I swear in front of her. It's probably a cultural thing as well. She is so sweet and so careful with her words that I find her too stepford wife like. AIBU for not welcoming this olive branch of friendship?

Oh and, same as Woobeedoo, there was a school mum that I had written off as too nice, too polished, too generous to possibly be genuine. Then I got drunk with her one day and now she's one of my best mates and I genuinely feel like an idiot every time I think of what a prick I was in writing her off like that.

Thanks again for the all the replies, ladies. To sum it up, yeah we have nothing in common. I have no bad feelings towards her, I just don't want her to dominate my lunch time everyday.

The cultural difference comment, I can see where my boss is coming from. We work in a male dominated place and she cannot communicate very well with some team members who seem awkward around her. She's very formal and bossy regarding work, I think that's how it is where she comes from. We are more casual unfortunately.
