DH makes his own appointments (hair cuts, doctor, dentist, etc.). He handles maintenance on both our cars, so makes the appointments for those. I make the tax preparer appointment, because having our taxes done is one of my "jobs". Other appointments, like for furnace/duct cleaning, carpet cleaning, tree trimming, pest control, furniture delivery etc. we talk about ahead of time and one of us volunteers to do it...sometimes it's him and sometimes it's me. Generally, the person who is going to be home to deal with it makes the call for the appointment.
