Hey Denya, Soooo I know everyone has a right to their opinion, but honestly I disagree with most of what you have said. However, I do agree that some, not all, people will be nice and not just straight up say "Yeah I clocked you" when questioned. They will use tact and diplomacy. It may just be how I interpret your posts, but they seem to be definitive, like every time someone stares it's because they clocked you and it's never because they actually like something about you. I've given plenty of women compliments on many things from their voice to makeup to clothes/jewlery and never once was I thinking trans or not... "And even if you question the staring individual, they will likely give you an excuse and will
never tell you that they were staring at you because they clocked you". One can also draw whatever conclusion they want from a compliment or comment so saying they meant this or that is hard. Here are some examples in my life that I find to be definitive of my "passing"; feel free to disagree.
1. Started talking to a guy who approached me. He came over one day and was super in to me. Checking me out, starting convo, flirting, touching, etc... Seeing that he wanted a more serious commitment, I told him that I was trans and then I never heard from him again lol His loss

He said he had no idea. Based on our interactions, I believed him.
2. At a club. Saw a friend there from a few years before I started transitioned. We were good friends and worked together. Anyways, we started talking and I told him who I was as he had no clue lol He told me that the friends that he was there with said to him "Who is that girl?? She's f@#$n hot!!!". That was before I approached my friend. Third party had no reason to lie to my friend especially since my friend didn't even recognize me.
3. Numerous guys and girls staring and then coming up to me at clubs or in public and trying to pick me up. Who knows, maybe they're all into trans girls

4. Many more similar experiences.
I've had people clock me as well or give me strange stares so I take that as being clocked although I'm not completely sure. Could be because I was scantily clad HEHEHEHEHE
So to answer the OPs question. No, I do not believe that every time someone stares, they clock you. At the end of the day, as long as people are nice/respectful to me, then I couldn't care less whether I'm clocked everyday

Once again I am not arguing or saying that your opinion is wrong. It just differs strongly from my life experiences. Nothing but love here

To me:
Staring does not = Clocking
Compliments do not = Passing
