Yesterday DH gave me his travel schedule for the next three months, as it now stands:
June 6-7 Manhattan
June 8-12 Guatemala
June 26-27 Manhattan
July 5-11 Colorado
July 31- August 21 Peru
All but the last, his annual vacation, are business trips for work. Also in July are a high-stakes board meeting and surely many more trips to Manhattan.
He travels like this for work all the time. He turns 65 over the summer (this year, apparently in Colorado). No wonder he is tired.
