I hate the Tube...
It may be efficient, but seriously, it's not a good place to be on when you're an Aspie with personal space issues. I very nearly freaked out many a time when I was packed in like a sardine in the Tube. Like as in started flailing out and hitting anyone nearby freaking out. Seriously.
Still, I navigated the Tube with more ease than my fellow traveller during that trip. I can read a Tube map and correlate it with a London map so easily it isn't funny.
I've lived for over 2000 years, and not all of them were good ones. I've made many mistakes. And it's about time I did something about that.
