I still remember when I first moved to the UK from the Czech Republic where people generally don't ask you how you are unless they mean it. A friend told me, "Hi, how are you?", and kept walking past. I said, "Horrible!" It took him a few seconds to stop, turn around with a confused face and say, "What?" I started complaining about being sunburnt and the conversation continued.
I still find it hilarious how confused he was when I actually answered honestly. I've always found the greeting "how are you" strange. Unfortunately, after 2 years living in the UK, I've grown used to it and I've started using it too. It's hard breaking habits like these but it's definitely worth it for our relationships.
Great read, thank you!
