I was on the Bakerloo line going northbound, and a guy with his dog were sitting in front of me (it was the transverse seats). He got off at Baker Street, and I got off one stop later at Marylebone. When I got onto Marylebone Road, he was already walking his dog in the opposite direction to me and we said hi.
It just made me laugh a bit. I'm sorry if this counts as low-quality, but I felt if the "to the guy with the speaker on the District line" posts are allowed, I guess this is slightly more positive/ amusing. #local
