Which Is The Favourite?

Brothers and sisters I have many: Though I know there is not any Of them but I love, yet I Will just name them all; and try If there be one a little more Loved by me than all the rest. Yes; I do think, that I love best My brother Henry, because he Has always been most fond of me. Yet, to be sure, there's Isabel; I think I love her quite as well. And, I assure you, little Ann, No brother nor no sister can Be more dear to me than she. Only I must say, Emily, Being the eldest, it's right her To all the rest I should prefer. Yet after all I've said, suppose My greatest favourite should be Rose. No, John and Paul are both more dear To me than Rose, that's always here, While they are half the year at school; And yet that neither is no rule. I've named them all, there's only seven; I find my love to all so even, To every sister, every brother, I love not one more than another.
