1) When I look in the mirror (or if I catch a glimpse of myself in the reflection of a store or car window), my perception of myself fluctuates depending on what I am wearing and how well I pass. If I am fully dressed (meaning having my wig and makeup on), I generally see a pretty girl. The exception to this is if I catch myself at an unflattering angle, like one that draws more attention than usual to my masculine-looking upper arms (especially if I am wearing a sleeveless top). In those cases I do see myself as a guy wearing women's clothing. Most of the time, though, I am satisfied with what I see.
2) I don't really care too much to be honest. I have been called "ma'am", and when having dinner at a restaurant with a GG, we were asked, "What would you ladies like to drink tonight?". I don't get offended when people refer to me as sir, though (I was addressed that way after showing a waitress my ID (male) to buy a beer). I understand that since I haven't worked on my voice, I will still sound like a man, and because of that, my main goal when going out is to be the best person I can be, to help give crossdressing exposure in this world in a positive light. Isha, I don't want to speak for you, but I think that we have similar goals in wanting to be "ambassadors" of the crossdressing world. By socializing with people I can increase the amount of people in this world who have had positive experiences taking to crossdressers, and I am hopeful that these people may defend crossdressers if they fall into a conversation where they are spoken poorly of (they could interject, "Actually, the other day, I spoke to a crossdresser in the grocery store, she was very pleasant to talk to.")
