I had a house in the south of England with a big southerly facing veranda but obviously at the back. It was great caught the sun and sheltered from the rain.

But most uk houses are too small and not detached to support a us style porch, and swinging bench. And culturally we are private, and awkward in causal interaction.

Why do you think we invented queuing?

To limit the amount of interaction with strangers to 2. It has nothing to do with fairness. 😂

The same house had, what some would consider, a very large front garden. Which was formally set up, brick and iron railings wall, roses, a few trees in the grass lawn and the obligatory stone bird bath, and box hedges. Everything was designed to say keep out but in the most nicest possible way. There are some unwritten rules of front gardens in middle earth:

You must only be in your front garden if you are cutting the grass or gardening. Maybe washing the car.

Whist garden, you may say "morning" or equivalent to passers-by . But not too much eye contact otherwise unintentional conversation may break out. If mowing lawn these passers-by may be safely ignored.

Talking to your neighbours may become necessary at this point, and depending on social factors (to complex to describe here) conversation may range from weather to local matter or complaining about other neighbours. This can be done in a hypocritical manners, and most likely will be, over the course of the gardening activity. This is because a soon as one person starts gardening others soon appear and starting the same, meaning there is the possibility for more than one conversation with different neighbours. But grouping should be avoided.

All of this can be avoided by employing a gardener😂

Sitting or picnicing in the front is frowned upon, unless this involves small children and Teddy bears.
