But in this you can also see the difference between an American and many others. I find the "how are you greeting" very tiring nomatter how I am. When I am being asked the question I internally go through an assessment of, how am I today, how interested is the person, how much do I want to share of this. It takes significant mental effort.

When I was a teenager I did a one year high school exchange to the US and for a long time I really struggled with the daily "what's up?". I was going through the above internal dialogue more than 10 times a day struggling to come up with an answer. Even, when I learned to just answer "yeah what's up" internally the dialogue would often still be triggered.
