I'M Not Invisible

I am a shy girl who's never been on a date But I'm twenty, and Mom says I'm just blooming late I'm destined to be an old maid without a mate Soon, I'll be past my prime Always a wallflower. Alone, I brood and sit Sometimes I'm a little quirky. I will admit But talk with me and you'll see, I've got charm and wit! I've mountains yet to climb I'm the guilty one that no one ever suspects Overlooked, as one of life's pathetic rejects Here's a clue: I used a knife, and other objects I committed the crime I'm the actor never given the starring role The person always shoved into a cubbyhole I'm not invisible! I have a heart and soul Might as well be a mime I'm the elusive word for your poetic line Look in a Thesaurus and you'll find me, Einstein We can be a couplet, two planets that align Let's make our poem rhyme Sometimes I feel like the hands of a broken clock Going nowhere fast should never come as a shock But where is the man who holds the key to my lock The one who'll ring my chime
