Explaining a gap after caregiving or layoff (Memphis)

I took time out to care for a family member after working as an electrician's helper. I am not sure how much to explain. What do you say in interviews?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.

Keep your skills fresh and mention anything recent. It shows momentum.
