Personally,
I'm grateful for these reminders. I'm sorta like David. My mind is like Swiss cheese these days too. So many appointments, household tasks, I'm really grateful they call to remind me. I always carry a pocket calendar with me everywhere. Because I'm hoping it will be one more place that I'll look in order to not forget. And with my husband's appts. and obligations too, I don't want any of them to overlap.
I remember when filling out medical paperwork at new offices, they always ask me if it's ok to leave a reminder on my answering machine. I appreciate this.
Dahlek...take a deep breath and decide this is one of the minor irritants in your life.

Visualize a poof of little pink baloons everytime you hear one.
