Twins

I have a twin sister and we just love to get together and talk and talk. It seems like we never run out of things to talk about. We like to get together in the late summer and do some early Christmas shopping for a couple of days. We stay up late and talk till we just have to get some sleep for the next day. There is something about being twins that is really special. And another thing, my twin sister also has twins. Isn't that something special?
