Prior to coming out I was always paranoid that I would out myself in some way. Somehow I didn't though.
When I came out though things happened quickly and a lot of people were very accepting. I was able to quickly switch roles around friends and was accepted. I'm so grateful for that.
There were several times where I accidentally outed myself after my transition was under way though. There were people who I had honestly forgotten to come out to and I would occasionally run into one of them. I'd walk up, and start talking to them like we hadn't seen each other in ages, because we hadn't. The look was always so great, it went from who is this, to you look familiar, to OMG, <male name> is that you? Luckily though it was never a bad situation and I think I've managed to run into all of the people who I think I'm going to anyway.
I can be a total ditz sometimes
