Yipee, a wonderful topic that makes my heart smile just thinking about it!
Turi, I've discovered the same thing myself - it's often those with the least to give that give the very most - truly wonderful! And to read of the massive kindness you did for your neighbour, dc3 - truly wonderful, honestly!!! And receiving the groceries was such a perfect thing - far better than an offer of money - and I'm so pleased for you.
Guess I've lived long enough to see so so so many random acts of kindness - yet each and every one remains special to me, whether it's someone with a cheery good morning while they hold the door open as I trundle through with my shopping cart, etc, or a huge kindness, such as you received Biker Chick. That must have been a truly horrifying time for you and no wonder the doctor's kindness still remains - gentle hug.
Finding myself in a slightly similar situation many years ago - having what we thought was great health insurance only to discover that 'round the clock' nursing in pediatric forever-care was not totally covered - I paid regularly to the hospital for 2 years, but even so was starting to fall behind with the interest applied, etc. But on Christmas morning, I found a present for me in my child's sock hanging on the end of his bed. A gift from unknown people - the Shriners - who had, without my ever speaking with them, taken it upon themselves to pay the full amount owing in full - plus they continued to pay until our little boy finally died. Each year at Christmas time, it is now my turn to 'pay them back for their kindness' - and yet, what they did during those sad years, was something that could honestly never be repaid.
But at the risk of sounding like the perpetual Pollyanna, gotta say that it's all the wonderful seemingly 'tiny' acts of kindness, not just the 'biggies', that make this my world so great - huge smile.
