There may be nothing more delicious than the quick exchange of shared amusement between strangers. Together, but alone, you notice the same thing, a burst of life that fills you with joy — a joy contagious enough to share, and then having shared to encourage outright laughter.
People are always looking to be amused… and in kindness… it’s only a mitzvah if we share our amazement at the world’s follies with one another.
Be on the lookout for delight. It’s there if you look for it. And fairly often, someone else will be looking too! Enjoy… and laugh!
