School uniforms, seaside holidays, traditions around Christmas, pattern of school holidays, the food we eat, (the everyday stuff and celebrations), red post boxes, letter boxes in the door, jokes about British rail, the weather, bonfire night, gardens, housing types, the shops and supermarkets, police, fire service and ambulance services, NHS, politics and political parties, the way our shop doors open, our use of language that differs from other English speaking countries, conkers, autumn colours, the flowers and vegetables we grow,
(I have friends/relatives that are immigrants and sometimes it's the little differences between countries that build up the feel of the country and culture, eh not all countries have school uniform, or half terms or access to the coast, or public transport, )
I went to the US and the extensively decorated for Halloween mom and pop general store was very different to our general sell everything corner shops.
