Also, I have read a few comments in this discussion about how fake American smiles and “how are you?”s are and I have to disagree somewhat. To a large extent Americans use “how are you” and “what’s up” as generic greetings but at the same time you can often tell when someone is using it instead of “hello” vs having 30-120 seconds to chat pretty easily. If my day is going well I make a point of telling the random person I’m interacting with why that is: “I’m doing great. The weather is so nice and I had a lovely cup of coffee on my back porch today.” Quick interaction, mostly meaningless, but to me it’s a nice way to break up the monotony. On the other hand if I’m having a bad day I don’t feel like hiding it but the trick is to not make it the other person’s problem: “I’m getting by. I blew a tire on the way to work and I just had all four tires replaced. But oh well, that’s just how irony works I guess.” Again, quick and simple and not the typical “fine” response. At worst they go “oh that sucks. Paper or plastic?” but more often it could result in a short conversation and I don’t think there is anything wrong with that.
