the importance of day planners

1. Every year I buy the same day planner from the same shop. Yesterday I sloshed in after being caught in a downpour and found that they had sold out. "But don't worry, Oscar will have them, just go down the street."
2. I arrive at Oscar's feeling cold and wet (and to be honest, slightly grumpy). No planners! "But don't worry, I can order one for you and it will be here on Monday. 20% off!"
3. Chatting with Pam on our way to the cinema, I tell her the tale. "Which kind do you use?" I ask. "Oh, I'm very specific with the planner I buy" she replies. "I always get the same one every year." It's the exact same as mine.
