Not sure I would count this as "passing" as cis, but its a pretty funny story I thought. When I went to the registry to hand in my name change application, I saw this girl working at the counter who was pretty good friends with my wife and we had talked several times since we always went to her anytime we needed something at the registry since she let us jump the queue and see her right away. So I did the same and went right up to her at the counter and said hi and put my name change application on the counter. She seemed to look at me like I was familiar but wasn't sure who I was. So I asked her "you have no idea who I am, do you?" She tried to come up with something, "I helped you before with a name change application, right?" "Ummm, nope" I replied with a little laugh. "I'm married to ≤wife's name>". I have never seen someone's eyes open so wide and jaw drop like that ever before. Maybe not a pass, but definitely don't look anything like I did before.
