How annoying can the permanently happy, loud, vivacious, forever joking, single 30-year-old London primary school teacher Poppy be? Surely there must be something wrong with somebody so sunnily optimistic? She likes her dope, she likes to party, she's learning to drive and to dance flamenco, she happily shares a flat with her best friend, Zoe, and she's always pulling the rug from under the feet of more serious and more pompous people. We learn about her through her relationships with people, she is perceptive, compassionate and has her own problems coping with life, and, through her eyes, we see the faults and graces of others.
