Query: She's a mighty powerhouse in a beautiful package.

Every song this dynamo performs is more powerful than the previous one. The words in her song, "Sometimes" jumped into my soul and expressed every word I feel about myself but could never have put together so well. Recently I searched for a way to explain my fears to my boyfriend...now I'll just mail this to him. Britney, ignore the jealous idiots who criticize you and you go, girl!!! They are so beneath you. You speak my mind better than I do! Thanks.
