Hi and good-bye

For the last several months, we have noticed this "Hi!" sign peeking out from under a bush on our weekly walk to Trader Joe's.
It always brought a smile to my face and I'm sure to all those who noticed it.
Yesterday, as I came upon the friendly bush, I saw that the "Hi!" was no where to be found. It has always been in the same place, but still, I searched all around the bush in hopes to find it. Alas, it was gone. I laughed inwardly at my disappointment.
It kind of made me realize how important a simple "hi" is to us humans. When we moved to NYC, we noticed how people just don't say hello as you pass or even make eye contact. One day, Dan said hello to an unsuspecting elderly woman and it startled her speechless. Since then, I have thought that one day, I would say hello to everyone I passed along these busy streets of NYC. I haven't had the courage to do it yet, but maybe I can just say hi to one person. Maybe that person misses the "Hi!" sign and needs it.
