What do you do when you're pissed off?

I ned some ideas. My last client of the day canceled 15 minutes before her appointment. This is the 2nd time in a row she has canceled last minute. I let her know how put out I was, but stopped short of charging her for the appointment...which was $85. My 5:30 slot is the most coveted slot, and gets booked a month in advance. Had I gotten more noticed, I could have filled it. On top of that my husband and kids made fun plans...and now I am stuck at home, by myself, without a vehicle. Blah. Help me with some fun ideas. The only good one I have is to go cut the grass.
