That's funny Icarus because even before transition and HRT,
I often had to prove I was the same person as on my passport
when all I had changed was my haircut and had my glasses on!!!
Sometimes I felt like superman, put the glasses on and I'd be
a wholly different unrecognizeable person.
I especially had problems getting into Ukraine.
It took the border ghard in the train 30 minutes, and a
supervisor!!! to confirm I was me. Plain incredible.
Land crossings as a TS would stress me out much more than
going by airplane. Usually, they are much less professional,
especially in third world countries. Crossing into China in Tibet,
another fun one!! I don't even want to try such things pre-op.
