How do I explain a layoff in interviews? (St. Louis)

I have an interview next week and I am unsure how to explain why I left my last job as a software tester. There are 15 people counting on me, so I am trying to be careful. I also do not want to seem like a risk. Do you mention numbers?

Thanks for writing this out. I went through something close to it 13 months ago, and it got easier once I kept a simple log of every call and form.

Say it plainly and move on to what you can do. Interviewers usually move on if you do.
