What really warmed my heart was when I mentioned that I was going to the dentist for an extraction (and a few other nasty things), but that I'd need to get the bus as we didn't have a car at that particular time. It was around the August of the first year of Gransnet, (I remember this because Ruby Wax was appearing at the Edinburgh Festival and Marmight, - who had a different name at that time - had commented that Ruby might want to come across the bridge to have tea with her, or something like that, anyway)!
When Marmight realised that she lived only a few miles away from me, she messaged me and said she would take me to the dentist and wait for me while I had my treatment, then bring me home again. I thought that was just so kind.
As it happened DH came with me, and I was actually ok, but that sticks in my mind - 'the kindness of strangers'. Not strangers anymore now, though.
