There are many callings. Some people teach.
Some people write.
Some people sing operas, and some train dogs. And some get up in the middle of the night to sit in the woods next to a stuffed deer head. I learned this today. I accompany women in court when they need to get restraining orders from battering husbands or boyfriends, or when they testify in assault cases or custody hearings regarding their children. In this line of work, it's something to be thankful for when business is slow.
