Daughter is embarrassed

From today's advice column:

DEAR ABBY: I'm a 15-year-old girl whose parents treat me like an 8-year-old. They not only refuse to let me see any movie that isn't G-rated, but they still cut my meat for me! Once a week we go to the park, and they still push me on the swings.

I don't want to tell them it's embarrassing because I'm afraid I'll hurt their feelings. Please tell me how to convey to my parents that I'm not a child anymore. -- OLD ENOUGH IN VIRGINIA

She is 15 and she is not yet able to express embarrassment to her parents? No wonder they treat her like an 8-year-old.
