Using a bit of that "out of the box" thinking most swab jockies are famous for: how about??
If the wife sleeps in another room, . . . and the anticipated bg's would be between the two of you, . . . why not harden the walls between your two locations (that would possibly receive any missed rounds flung at the bg) and have a plan where you both hunker down in your respective rooms?
When our son lived with us, . . . he knew my "hunker" location below him, . . . and my wife's.
We knew his hunker location.
All were somewhat hardened against a "miss" from one, becoming a hit on the other.
But the devil himself could not have walked through the middle and survived.
Not all houses can be "planned" that way, . . . but if it is available, . . .
May God bless,
If you can breathe, . . . thank God!
If you can read, . . . thank a teacher!
If you are reading this in English, . . . thank a Veteran!
