I've had the last few days alone and have again indulged my wish to try living en femme. I hit a new milestone the other day when I realized that I no longer feel like an imposter when I wear a women's outfit. The key for me seems to be interacting with other people, and hearing the word "ma'am". These last few days, I've not only gone grocery shopping while dressed up but also bought an inner tube from a bicycle store -- where it's necessary to tell the sales person what I need -- and made a return at REI. My "female" voice isn't very good, but no one has batted an eye. Talking to people builds confidence for me much faster than picking up goods and pushing them across the counter while minimizing the need to speak.
