I've always wanted to find out 'cause I always feel like a big dummy when people ask us.
We finally decided to just tell people who ask, "yes, we're identical".
One time, this lady asked us (just like this), "Are y'all twins or are y'all sisters?" Now, I didn't mean to do it, honest, but before I could blink I said, "Both".
My sister was like, "B-o-n-n-i-e!" and that poor woman's face turned so red.
Honest, I didn't mean to make that lady feel stupid. I really felt bad. Well, kinda...
