I don't think you'll get an honest answer for this a lot of the time, often team members might not even directly know why someone was laid off

>When was your last vacation, and how long was it?

This is a bit tough too, it's very subjective. I personally like working, and while I encourage my employees to use all of their vacation time, I rarely do so myself (I spread my time around as individual days rather than large chunks).

Also depends on your audience. Parents will answer this much differently than individuals.
