Same for me. I haven never fooled with them very much. I use a tweezer if I notice one of those little buggers getting too long or trying to point in the wrong direction. ;)
I was going to say I've always done that myself, but I have just remembered that when I was in junior high there was a cosmetology class in the school (it was a Jr./Sr high school and there was an option for seniors to complete the coursework and practicum necessary to get their license/certificate). We could go during our study hall and pay a very small amount to let the students practice on us. My eyebrows and fingernails have probably never looked as good as they did when I was 13-14!
