things you can get done while on hold...
*unload and load an entire dishwasher
*brew some iced green tea
*unload and load some laudry
*walk the dog (not really, but probably)
*give up and hang up
*call back in a few minutes on your cell to make the appointment
*try to call back on your cell to tell them that your home phone is still being held hostage by the hold button
*keep trying on your cell, since now your cell is giving you that busy beep beep beep
seriously, my home phone was on hold for over 20 minutes!
