You need warm cups of tea, or the cold feeling of your glasses on your nose, or rain at night and bird song in the morning, or the cake warmth after putting on a baggy jumper, listening to music whilst washing up, dancing in the kitchen when alone, smiles at strangers, dark bus journeys, the smell of fresh laundry, the rain on your cheeks or the sun in your eyes, bad jokes, the feeling of old books and the smell of new ones, using pens for the first time.
