Doesn't have to be a big thing.
- I was ill a few years ago, acutely for about 2 months and probably another 10 months after that. Particularly in the first two months, a friend of mine practically gave up all her time every day to sit with me, help with washing and cleaning and keep me going. She was a huge support to dh and the dc and we won't forget her kindness.
- During the same time, I had another friend who would post me little cards every week or two, just to remind me that I was loved and appreciated.
