I dealt with younger troops during my time in the Army. I found routinely that they:

Could not sew, mainly buttons but simple darning.
Could not cook, other than microwave popcorn and stuff you could nuke
Did not know how to do laundry
Could not balance a checkbook
Knew next to nothing about simple auto maintenance

and my one favorite

Couldn't operate a lawn mower ("We had gardeners" she said)

No stories, personal observations. But to make y'all feel better, if they were my troops, they were shown how to do some of the stuff I classify as routine living.
