A typical day schedule of mine look aproximatly like this:
04:45 wakeup
07:50 take children to school
12:45 tentative religious meeting
13:15 take children from school
19:00 religious meeting
Then we have the weekly schedule on top of it, with at least one more weekly event each day.
Then we have the monthly schedule on top of it.
And now I add all my business/work events.
Now, while I am working on my computer or in a meeting, I would like to have a different and specifiable ring for each event, so I'll know what it's about without having to take a look at the phone, especially if it is in my pocket.
In other words, we need event specific rings for the same reason we need contact-specific rings.
