TWINS?

For about the umpteenth time (hint, that's a lot), someone asked Sister and I if we were twins! We totally don't get it.

Sister has curly, red hair and brown eyes. I have short, straight brown hair and blue-green eyes with gold flecks. We're close to the same height - both short - but Sister weighs about 20 lbs. less.

I think it may be our mannerisms are very similar, and it's probably very pronounced when we're together.

Below is one of the most recent pictures of us together. What do you think?
