I can understand where you are coming from because I too hate when people exaggerate the issues they may or may not have just to fit in (think the word "emo" or "c*tter")

However...it is very possible to have obsessive-compusive tendencies about certain things. I am this way with writing. I will "have" to write and erase and rewrite certain words or letters in my notes and homework for no particular reason, over and over again. Do I have OCD? Probably not. That's where the word tendencies comes in. Unless she has been seen by a doctor or therapist who can diagnose her case, she very well might have this disorder and not be aware of it. Maybe she has it worse then she is letting on to you..who knows? I feel for her because it is hard to have certain quirks like this without having it to a bad enough degree to be taken "seriously" by therapists...hence the word "tendencies" again.

I hope this helps some and isn't insulting. Have you suggested that she see a therapist or doctor?
