Anarchy needs rules as I've shouted on many summer days by Heavitree paddling pool, if you host a dinner it's your house but here are my house rules.
1 Play fair, bring what food you can and share it out.
2 More people means more people to cook and wash up, less effort for everyone, the kids need to share the load too.
3 Turn off the screens for a while, get the kids busy and they might not bother with them for hours.
4 My house is Straight Edge, no drugs legal or illegal.
5 Safety first, pick people you know or meet a few times first.
6 If you don't know people very well put valuables and keys upstairs.
7 Mix it up, dinner is lonely for lots of people, if you have a big family ask a singleton or elderly neighbour.
8 Tell us about it and send pictures and recipes.
9 Keep it simple, this is about fun not showing off, if you are a good cook share skills.
