There have been times when other people (those I know, as well as strangers) have been of great help to me, in a variety of circumstances and situations.
Sometimes it's because they:
1. showed a warm smile (or even just a small "Mona Lisa")
2. have said a few words of encouragement (or showed it in their facial expressions)
3. retrieved some item for me in a supermarket - really, some of those shelves have been set up for the Jolly Green Giant (ok, maybe not - I do realize that people are growing more tall and more beautiful than ever)
4. opened a door for me (they've been men, women, children, ...)
5. did something for me when I know that it meant sacrifice in their own schedules or lives
One time (at the annual LA County Fair - big event every year at the end of summer/beginning of autumn), a lady (a complete stranger) heard me talking to my family about some hot pink yardsticks that I saw some people carrying, that some vendor had been randomly giving away to people. I was just commenting that I thought that they were pretty. You could not miss these yardsticks - very noisy color, you see.

(I like measuring devices such as yardsticks as I love to sew, alter, & mend...clothes, mostly.) All of a sudden this lady appeared out of the crowds and gave me her hot pink yardstick. I was...I didn't know what to think. I was so surprised. I smiled, thanked her, and she gave me a big smile. I still have (and use) that yardstick.
