13-month résumé gap, advice? - 19 weeks in

I took time out to care for a family member after working as a customer-service rep. I have been trying to stay organised about it. I am not sure how much to explain. What do you say in interviews?

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

I was hired after a 13-month gap. The manager said the skills test mattered more than the dates.
