I must admit to a long-time fondness of reading church signs. I love the messages that are brief, to the point, and easy to remember for longer than a moment or two.
Catholic churches don’t do this (not around here), so I’m sure that contributed to my interest.
The one I ran into most recently said, simply:
“Be a fountain . . . . .
. . . . . not a drain.”
Great advice! I want to remember that one.
