Unibrow, not OK.
I do like groomed eyebrows, Cynthia uses the clippers on hers. Plucking or waxing is not ness. to be well groomed though.
The whole "how far they can extend" is a girl thing in my opinion. Also, I can't imagine trying to change the grooming habits of someone I am dating. But whatev.
Now before I start dating someone, or if I am trying to...? I might make mention, you know if prodded by a friend or something like that.
