My boo boo in office

Put my name up for escort duties way back in June. Clean forgot about it. Now my bangkok trip clashes with the seminar (read my escort duties). Colleague was sweet enough to agree to cover me for the one day that I will be gone. Director sent me a mail on how I shld not repeat this. He was disapproving but yet kind.

Sigh....felt lousy the whole day.

I shall not whine too much. It takes a genius to whine appealingly someone once said. God knows who, cant quite remember now. Any one willing to help me out here?
