You have a very good point. The problem, when there is one, is when people make the assumptions that would lead to questions, and then don't ask the questions, and presume that I'm married, or presume that I'm wearing the kippah because I'm a rabbinical student. That's what I want to avoid.

Not wanting to have to constantly answer questions is just that I myself don't always have the time or energy for that, when I want to just get my grocery shopping done, or when I want to dance and be social and be me-the-basic-self rather than being me-the-rabbinical-student.
