I used public transportation exclusively when I lived in Brookline, Mass. The "T" cost 80 cents, including transfers to go from one place to another. The stop was 2 blocks from my house. I loved the T ... I could go anywhere in Boston to explore, and have a ride home. That was the last time I lived anywhere that had public transportation. Mostly I used it to go to grad school and back. I explored areas of the city before I caught the T to go back home.
It did gross me out one day, when I looked down on the tracks and saw a lot of rats running around. Thank goodness they didn't have wings! These were wild rats, of course. I got over my fear of pet rats when I met a lady who had a pet rat and persuaded her to let me hold him. I carried him around her house for half an hour and he was a right nice fella. So I'm no longer afraid of pet rats. He was cuddly.
After that, rat lady asked me to take care of her Clydesdale stallions (6) and her miniature horses. She was a lady of extremes. I had never taken care of a horse in my life. Although I was willing to learn, my husband put his foot down due to the danger he perceived in me doing that. I think he was right, but at the time I was a bit irritated that I couldn't learn something new and have an adventure. The Clydesdales were a whole lot bigger than me, so they were at bit scary. Plus my whole family was with me and I had to cover my little girl's eyes. Clydesdales don't wear underwear.
