If my wife slept with any other normal human I may be upset by it. If he got her up the duff then yeah that'd be awkward. If my wife slept with a welshman it wouldn't bother me. I'd just bury her in a ditch somewhere and move on, there would no longer be any earthly purpose for her after that. No emotion involved, she must have malfunctioned in some manner and I'd be putting her out of her misery.
