And for the record, reneges means "To fail to carry out a promise or commitment." It doesn't necessarily mean someone lied or was dishonest at all.
As you can tell from my previous post, I know what renege means. For the record, it means "to go back on a promise or committment. to break a promise or break your word." (Merriam Webster) Which is a bit more willful than "fail to carry out". If I fail to get all the grass mowed, it is not the quite the same as promising I would do it and then choosing not to.
As for you other post, I fully understand your position and think that you are utterly wrong. But I'm not going to get into a further p!ssing match with you, as that would be pointless. Since you seem to be one of those people who has last-word-itis, have at it.
