I always tell students that writing a poem and publishing it are two quite separate things, and you should write what you have to write, and if you're afraid it's going to upset someone, don't publish it.
Wendy CopeThe interesting thing is that you don't often meet a poet who doesn't have a sense of humour, and some of them do keep it out of their poems because they're afraid of being seen as light versifiers.
