I ended up with three sets of siblings (two sets of twins and one set step-siblings) and two sets of cousins in my class. It seems like everyone is related to someone else in the class. Today was the first day, so it's hard to tell if I'm going to have problems, but if anyone has any thoughts, I'd appreciate hearing them. This is my first year teaching. It's a bit odd, that's all I can think. I thought they usually separated them.
