"We find what is funny"

I recently met 'Isabel', a lovely woman who is rapidly approaching her 90th birthday, and her daughter 'Rhea' at my day job. Isabel is an intelligent, alert lady who despite a serious heart condition displays an active interest in others and her environment. Rhea has a good natured, healthy, fresh-air feel about her, and clearly enjoys her mothers company. Isabel proudly told me that Rhea works out every day, walks and bikes on a trail nearby their home...and that she has had MS for 30 years.

They asked questions, told stories and laughed. While they were laughing Isabel piped in, "We laugh all the time. We think so much is funny--we find what is funny. That's what we do."
