Addendum.

The day that I heard these anecdotes, the (lesbian) sister popped back into the apartment five minutes after she left, which she never does.

As it turned out, she was headed to rehearsal for that one lesbian feminist chorus she's in, and she had taken off her wedding ring in her sister's apartment for some reason and had set it down and then had forgotten about it, and she had to go back to get it so she could wear it to rehearsal.

"People would be talking!", she cracked.
