Hmm... yes, I have two. Sisters, both I'm afraid. They're quite a handful although I suppose that's to be expected. They have a great deal to live up to after all.
[ Peggy herself was quite the tomboy as a child, always getting into mischief. It's a difficult legacy to outdo. ]
Perhaps with time, you'll grow as close to your own sister. If there's a will, there is usually a way. Of course, those aren't the only kind of family ties. Close friends can be just as dear.
