Growing up?

So is this how life goes when you are raising a pre-teen daughter? One minute she is wearing ruffles and pigtails and the next minute she is sneaking clothes out of the house. This morning I noticed the outfit Gabrielle had set out consisted of a tank top and an old pair of jean shorts, ok not so bad but didn't I just go out and spend almost an entire paycheck on new school clothes? Nordstrom, Abercrombie, etc. Yea, she's spoiled. So I mentioned to her the nice new shorts I had recently purchased for her, and with a little argument from her she agreed to wear the new ones. Well, Gabrielle goes to my moms every morning and on this particular morning she took her clothes with her to get dressed. I saw her grab her "new" shorts and a belt and "Goodbye mom, luv ya" off she went. As she was walking to the car after school I noticed those dingy, tad bit too small jean shorts on her. When I asked her when put them on, I was thinking she was going to say the other shorts bothered her but she said "I put them on at Nanas" WHAT? "Gabrielle you hid them from me and purposely took the ones I wanted you to wear so I wouldn't get mad?" You know what the kid said! "Yes" She totally admitted lying and being deceitful to me. I never remember doing something like this to my mom, I was perfect, I was! What am I in for?
