My daughters are twins. Both are right-handed, but lots of mirror things. Their teeth ALWAYS came in as opposites, and often fell out as opposites as well. I’m thinking there were moles too that were opposites - or something.
They are “identical” - but their styles and interests are VERY different. They both are great kids though!
On Saturday, I enjoyed dinner at the home of a good friend who gave birth to two sets of identical twins. The first two were girls; the 2nd set were boys. Unfortunately, something went awry and one of the boys died in utero.
