Sandy didn't understand my request to review something in the future. How can I be so misunderstood? :)

This may be a problem. I told Sandy, "Remind me to review Roomba Repair Situation on Saturday." She replied:

Hrm. I couldn't find this anywhere. Might you already have deleted it?

I put this on the calendar:

#1 Sat, 7/26 Review Roomba Repair Situation
- email reminder at 8:00am
etc...

I have the full message, but it is not yet clear to me why she thought I was updating or deleting something.
