Let's say I have 2 sets of twins and I grab 1 twin from each set. If these 2 non-related twins introduced themselves both as being twins but not being related to each other, how would they say that?
Would they say "we're twins, but not...
- to each other
- with each other
- ...something else??
Obviously, they could say that "we're twins but we're not related." But I'm wondering more about preposition choice in this case, so please address that aspect of the question.
