When you disagree with a friend or have to part ways in a hostile manner, for any reason at all, don’t ever dig his grave too deep. Do not denigrate him recklessly. Exercise caution over your emotions and restraints over your tongue. Perhaps you may reunite again. Words uttered are irrevocable; and recanting your words rarely fully control the damages already done. Some of your audience only hear the word - go, they turn deaf to your subsequent scream of come-back.
See how Obasanjo is trying strenuously to mend Atiku’s reputation after he murdered his former vice, verbally, with all those unprintable words he has said and ‘printed’ for over a decade. Should he ever have been that spiteful to utter those words?

And Oh ye, of little tolerance who have taken this elections issue personal by abusing people; spewing vulgar, uncouth and hate languages at others of different persuasion; what hath thine stand to gain from that?
Listen! Among political leaders, the blood of common interest is thicker, far thicker than the water of political loyalty. That’s why you see Omisore back in the APC today. That’s why Obanikoro is the State witness against Fayose in the Courts now. That’s why Obasanjo tore his PDP membership card and is today leading their assault against the APC. And that’s why Atiku would make a list of guests of honour at Buhari’s child’s wedding. And you may not.

Keep your friends, you may need them one day. Neither Buhari nor Atiku would be easily accessible to you but your friends would be.
Think! And deeply too.
