over night company in an empty house

I had a couple staying overnight with me last night, good friends since way back in our college days.  We had a lovely visit with other mutual friends, dinner and a ball game then came home and went to bed.  I did still have a bed for them and towels in the bathroom so they weren't roughing it too much.  They did marvel at my nearly empty basement as only friends who had seen it at its cluttered worst could. As they went to bed they asked me to wake them if they weren't up by 9:00am. None of us realized that my handyman (who I knew was coming to do some work today) would arrive at 8:00am and immediately start working on a job, involving lots of hammering, in the basement directly beneath their bedroom. Surprise!! Not my best hostessing moment but they survived it with good grace, at least after I served them coffee.
