do not under any circumstances give a librarian your true name, accept a gift from it (especially food or drink) and for god's sake never stray from the path in a library.
@raphaelmorgan i didn't use my legal name before i came out, it was certainly interesting to see who had been accommodating that and suddenly couldn't when my preferred name became jen.
it's a simple kindness but it means a lot when people realize it's no different from saying "it's kate, not katherine"
