A late apology

Dear friend,

So sorry if we've gone too far,
never in our intentions to did you any mar.
It's just seemed to escape our radar,
jokes and jests just came out without any bar.

So please accept this apology, dear friend,
though it may be too late to make any amend.
Signs you've sent we should've got to comprehend,
but still, jokes and jests were out in the end.

Never again, I promise you that,
or you can force me to eat my hat.
Whether I have one or not is not the point to look at,
the important thing is what I'm saying out flat:

Please find it in your heart to forgive us, dear friend.
