I love my father. I've been around him as long as I can remember. People often talk about us as being complementary, as if I were as great as he. I don't have much to offer, so I just show everyone how glorious he is.
I have to show my father's glory to everyone because of my big sister. She is so controlling and makes me be around her all the time, like a slave. Now I can't be me without everyone seeing her first. She also has a lot more stuff than me, which makes her special. I give in to her demands, but still stay with our father. I can make do with my situation by showing how great Father is, but her intervention makes her seem like the successful daughter while I get tossed around. Now I admit this is mean, but I mess with my sister often, picking at her tears. Somehow, we all live on.
Who/What am I?
