At first, I thought it is part of a new culture that I need to get used to. After all I was brought up and grew up in a very different culture. Then I realized the problem is that a lot of Americans are lack of common sense or social sensitivity.

They are pretty much ignorant about things outside their city limit where they live.

I was asked by one of my coworkers on 4th of July, "So, do Chinese celebrate 4th of July?" This is the MOST STUPID thing I have ever heard. "Well, Chinese do have 4th of July EVERY YEAR. So do Japanese, Korean, British or the rest of the world. But I do believe that only Americans celebrate that day," I told this girl. Maybe we should rename Independance Day as American's Independance Day?

And I thought my own family could have known me better until my mother in law asked me this several years ago, "which part of Thailand are you from, dear?" After I had married into this family for half a decade, MIL still found the far east is way too far for her to handle.

They try hard to be sincere and want to have a conversation with you but they do not intentionally want to know you as a person.

I was asked by one of my coworkers at my craziest busy working hour in the morning, "So do you cook a lot of Chinese food?" EXCUSE ME? Do you REALLY want to know? Or, "how many brothers or sisters do you have?" Well, if you are not demented or mentally retarded, I have answered the same question the fifth time since I have known you. Maybe I should put up a sign on my forehead so that you will remember next time when there are only two of us sitting in a room. I'd say knowing when to shut the f*ck up is the key. Yapping for no reason is a SIN.

They are rude when you do not matter to them. 

Take talking on a cell phone in the public for example. First of all, the purpose of carrying a cell phone with you is so that you will not miss an EMERGENCY phone call, but it's NOT that you can carry out your private conversation from your living room to the public. Where is your courtesy, really? The rest of the world do NOT need to hear what you cooked for dinner last night while we are shopping at Meijer's, or while we are at the grocery checkout, or while we are on a train ride from Detroit to Chicago.  

Talking on a cell phone or texting while driving is just WRONG. They are dangerous on the road just as much as people of DUI. It becomes ANNOYING when they drive on the left lane. Speed up, slow down, speed up again, then slow down. Well, move the f*ck over to the right lane if you want to talk on a phone on the road. Multitasking does not apply on the road!

Not to say that people leave their grocery cart in the middle of hallway, peolpe walk in the middle of the road in the parking lot thinking that pedastrians have the right of way, or a group of cyclists of 10MPH in the middle of the road blocking the traffic at 7o'clock in the morning.

So people, where is your social sensitivity?
