I hope this finds you in the best of your health and spirit. I am extremely sorry not to be able to meet you last evening at the Rotary Club building as we had decided earlier. You must have taken it ill. But I was helpless due to unavoidable circumstances. Please accept my sincerest apology for it.
I am sure you will make it convenient to see me once before you leave for home. Please excuse me for the inconvenience caused to you.
With best wishes and kind regards,
Reply to above apology letter
Your letter communicating your inability to make yourself available at Rotary Club building was duly received. On not finding you last evening as earlier decided I had conjectured that some urgent work might have interrupted your plan. So no cause for worry please.
I thank you very much for your suggestion to see you once before leaving for home. I shall try my best to see you at your residence tomorrow morning. Rest is O.K.
Nothing more to pen. More when we meet.
Yours as ever,
