You know when people say "I'll forgive you but I won't forget"? Doesn't this sound like an unforgiving mindset? While it's true people generally don't forget, to say it sounds like "I'll hold onto this. I won't let it go. Although I might not scream at you or hurt you in overt ways, I won't be as loving as I could be. I'll throw this in your face when I can in lots of small ways and end up punishing you forever."
