Oh my! A 1x1 should be enough @Freddyt ? (Just kidding. ) Sounds like your wife cares a lot.Sometimes a 2x4 upside the head helps to get our full attention before you start.
ETA, it came to me, I'm not sure it ever comes down to the lies (though of course it could), but maybe more so it is about deceit? Which can be spoken, not spoken; in words or actions or deeds, or whatever. That is what I think actually belies the trust. And belies of course meaning, contradicts, or betrays.
Hope that makes sense.
