Do a Favour

In the post office lobby, an old woman approached a man and asked politely, "Sir! Could you do me a favour to write an address on this postcard?"
"Sure!" The man did it as he was asked.
"Thank you very much!" The woman continued, "And, could you write down a few sentences for me?"
"Alright!" The man did it as he was asked and said, "Anything else?"
The woman looked at the postcard and said, "Please ad a sentence at the end: Sorry for the hen track!"

If you were the man, what do you feel......?
