Do you have a time that you won't take phone calls?
For example, do you not take phone calls during meal times? after a certain time at night?
It's almost 11pm here and there's been AT LEAST 3 phone calls in the last 5 mins - all from different people who don't even know each other so I know none of them would have had a related topic.
I'm laying on the bed thinking "seriously? You can't call me during the day - don't call me when I've finally got all the kids to sleep and I'm heading there myself!"
