One of my friends dared me to walk through my neighbourhood to the local park in a girls' top and wig. Never one to care what society thinks, I put them on and set out. I thought I'd feel nervous, but oddly, it was the least self-conscious I had felt in... I don't know. Maybe ever. I didn't pass at all, nor was I trying to, but just wearing something clearly feminine and having long hair (another first for me), made me feel... Almost giddy, really.
That was a few years ago.
