Don't call someone five times in a row if they don't answer.
He may be driving, in a meeting, sleeping, talking to someone, or simply unable to pick up the phone.
If the matter is not urgent, one call and one message is enough.
Respecting someone else's availability means remembering that one does not have to be available every minute.
- I don't disturb unnecessarily.
— I write a message first.
