Friending weirdness

[hils]

A couple of days ago someone left a comment in my friends only post saying they'd added me and would I mind adding back. Not a problem. We had similar intrests and she seemed nice enough so I friended her. She still hasn't friended my journal. LOL.

Now I've just been friended by someone who seemingly has no similar interests to me (apart from Torchwood which isn't really a big fandom of mine), she hasn't commented on my friends only post and we have no mutual friends. I'm holding off friending her back for the moment
