That's a recipe for disaster along multiple dimensions....when boyfriend/husband are teaching girlfriend/wife and have no idea themselves what the **** they are doing...
There's nothing I like better than teaching women and kids who've never handled a firearm before.
There's nothing I like less than teaching grown men who believe they are the prodigal sons of John Wayne and are therefore born with a complete and perfect knowledge of all things firearms-related.
When the second group is trying to teach the first group, though, tears and terror are in the offing.
