I AM the annoying sibling!!!!

I have an older sister. We weren't raised together, and we just found each other a few years ago. I do not know how I ever made it this far in life without her. I am glad she's here now and I love her to pieces.
She'll be the first to tell y'all though I'm HER baby sister and therefor I AM the pest. ...She wouldn't trade me though.... at least I don't think she would... well, maybe try and sell me on E-bay? Didn't Shel Silverstein write a poem about that?
