Actually it was yesterday:
My daughters took part in the London Moon Walk - 15000 women (and some men) 26 miles walking overnight wearing a bra, for breast cancer charities. I saw them off, went back to the elder one's flat - that was an achievement in itself, I don't know London buses, and they took me back there when I first arrived, saying "now pay attention so you know where to go", and back in for the start of the walk, and then I caught the bus back and found that one didn't have any signs or announcements on it, and I still managed to get back to the flat - in the dark, that's a big deal for me - and back in to Hyde Park the next morning to see them arrive
Took them to Wetherspoon's for breakfast afterwards, and then back to the flat where they slept it off
and woke about 5pm and we ordered a huge amount of pizza to be delivered, which I also paid for. I just sat in the same room reading and watching the telly (quietly), but what touched me most was that they were so appreciative that I'd stayed there with them while they slept, when I could have gone back into town and then back to Cambridge.
Amnazing feeling to be told that your very presence means a lot to someone.
