I ALWAYS say Thank you to everyone. Even my kids for doing the smallest thing for me. In the summer when I am out and about on my scooter, there will often be an elderly person sitting on the front stoop. I slow down, give them a smile and a good morning. Total strangers, and it makes their day and doesn't hurt me a bit.
My favorite person to quote is Winston Churchill. And not just his inspiring quotes but those that have a bite. Maybe that reveals too much about myself but........ what the hey!
Here is one:
At a dinner party Winnie drank a lot (as usual).
"Bessie Braddock: “Sir, you are drunk.”
Churchill: “Madam, you are ugly. In the morning, I shall be sober.”
Eventually, all things merge into one, and a river runs through
it. The river was cut by the world's great flood and runs over rocks
from the basement of time. On some of the rocks are timeless raindrops.
Under the rocks are the words, and some of the words are theirs. I am
haunted by waters.
