How little theft there is. I was always told to always mind my bag and make it clear I’m holding it tight. Now I can freely leave it beside me, sometimes not even look! I’ve had friends leave a purse on a table in a restaurant and I made jokes about how easy it would be to steal it. Just a lot more relaxing in public due to less theft.
Another one is how less physical fighting in schools there is. From a young age I was always told “if someone hits you, hit them back harder” but when we moved to UK my dad told me before my first day of school “if someone hits you, tell the teacher”.
