Things of note as I went:

• An eager man well into his thirties pulled a wheelie alongside a clearly disinterested woman. Wheelies didn't even impress girls when I was ten.

• An elderly couple strolling lazily while eating ice creams. A touching heart-warming scene until the woman let out an almighty yeasty bottom-burp. I failed in not laughing. She seemed as shocked as me.

• A couple of Eastern European descent having a massive argument - why do arguments in other languages always seem romantic or funny?
