My mother was a worrier. When we were coming home from a trip and I was driving, she would say, "I wonder if there will be a parking space near the house." If a neighbor had a leaky pipe in their home, she wanted to call the plumber to have him check our house before we got a leak.
Any little noise that our car made had to mean a major repair job in Mom's eyes. And, her first reaction to any illness was that it was probably serious, would lead to something much worse, and would entail a huge doctor bill.
