I have always found humor to be essential in fostering relations with friends, teachers, children, and parents. It makes building relationships a joy and fun, especially during these very trying times.
Humor, Seriously by Jennifer Aaker and Naomi Bagdonas is a treat to read. I love how they look at humor from the perspective of those who use humor in their work, e.g. stand-up comedians. Their perspective and talent are inserted throughout the book, which makes it easy reading, entertaining, and most helpful.
