Me: "Thanks. Congratulations on your upcoming adoption!" (Thinking to myself that it's going to be awkward if this conversation continues and I have to tell her B&C are not twins).
For the record, the boys were not wearing matching outfits and the nice lady at breakfast was the third person to assume the boys were twins in less than 30 minutes.
Yep, pretty much any time we go out in public, we get asked over and over again, "Are they twins?"
