I feel weird calling my sister "my twin" and calling my twin "my sister." I feel like neither of them are just right.
When I use "my sister" to people who don't know about Baby A, I usually get a weird look, sometimes followed up by a question. Like "You have a sister in the same grade as you?" or "Why do you live with your sister still/work with her/practically share a bank account?"
But I feel like calling her "my twin" makes me sound... I don't know. Like I am bragging maybe. Or like I want everyone to know how *special* I am because I have a twin. Which is not the case, I just don't want confusion sometimes.
So I walk a fine line between feeling like I advertise my twin-ness and getting awkward looks and questions. I feel like most twins usually use "sister" or "brother," like I do, right?
