My first outdoor cooking memories are full of erratic British summers, Dad swearing at a barbecue that he couldn't put together, and eventually eating charred sausages, feeling brilliant.
Writing for adults often means just increasing the swearing - but find an alternative to swearing and you've probably got a better line.
There is no such thing as too much swearing. Swearing is just a piece of linguistic mechanics. The words in-between are the clever ones.
I simply do not think that yelling, swearing, threatening or belittling will get you to the place you want to be faster than kindness, understanding, patience and a little willingness to compromise.
Writers used to make such wonderful pictures without all that swearing, all that cursing. And now it seems that you can't say three words without cursing. And I don't think that's right.
