I am in earnest - I will not equivocate - I will not excuse - I will not retreat a single inch - and I will be heard!
And now, excuse me while I interrupt myself.
There's no excuse for rudeness.
There is no excuse for a well-dressed gent to wilt in the warm months.
There's no excuse for losing for me.
If it's achievable, there's no excuse why you shouldn't be doing it.
There is no excuse for perjury - never, never, never. There is truth, and the truth demands respect.
We excuse our sloth under the pretext of difficulty.
Excuse my scribbling, it is late, and I have a poor candle.
Any excuse will serve a tyrant.
