Explaining a gap after caregiving or layoff, customer-service rep here

My résumé shows a gap from a layoff and some health issues. I would rather hear the honest version than the polite one. I have done some volunteering and a course during that time. What do you say in interviews?

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.

Keep everything in writing and save the confirmation numbers. It saved me later.
