Do you talk about your twins as if they're one child?

I noticed the other day that I always refer to my twins as "the twins" as if they're one child. "The twins are in first grade. The twins ride the bus. The twins get home at 3:30"
Granted it's not difficult to lump them together as "the twins" since they do almost everything together. They share a bedroom, they even still bathe together. They do each have things that are their own, like my son was in soccer in the fall and his sister wasn't. My daughter is in dance and baton... obviously her brother is not. They are in basketball together though.

But I notice I rarely refer to them individually. I rarely say "Tyler is doing great in school, and Tristan is doing well also." Instead I'll just say "The twins love school, they're getting all A's."

Do you do this too?
