You know you are feeling quite at home around your husband-to-be's family when you decide to color and highlight your hair... and are willing to walk around the house with the goop on your head (instead of hiding out in the bathroom). While your new step-daughter -- and her boyfriend -- are lying on the sofa watching a slasher movie.
I figure I have to give them something to giggle about behind my back. She already laughs out loud to my face at my "bed-head" first thing in the morning when my hair looks particularly pineapple-ish.
