Great thread.
Quite a few. One in particular stands out. Watched Children's Hospital on BBC one summer after having my tonsils out (1999?). It was on every week day morning just after the news. There was a little boy on there who I think was called Ali(?). Absolutely lovely- making jokes and just being incredible despite having what I think was leukemia On the last episode the screen went blank and we were told he'd lost his battle and died. Even though I was only young myself, it really stuck with me. I hope his family are well and, if they ever saw this, can take some comfort knowing that, 21 years later, their little boy is still fondly remembered in the heart and mind of a stranger.
