Actually there were few incident during my fresh off the boat era.

1. Drinking water out of water fountain. It seems like people just bent down and the water comes. But when I do the same thing, there was no water... Reminds me of Nepal Khane Pani Sasthan ko Dhara.... Didn't realize there is a push button.

2. First day in class room in an American University. The Professor entered the room, I stood up... Good thing, I didn't say " GOOOD Morning Sir"

3. Of Course, this happened to my friend, who was in IOWA during his fresh off the boat era. "MY go to Toilet"

4. I will never forget my first visit to Subway. I pointed the picture to ordered a sandwich, thinking that was easy.
Subway: "What kind of bread?" 
(I knew only Nanglo Pauroti, and some other Pauroti. All looked same. At the same time I don't want to look dumb)
Me: "What kind you have"
Subway: Whole Wheat, .... Italian... 
( I could catch only Italian)
Me: "Italian"
Subway: "What about cheese"
Me: "What do u have"
Subway: "American, Swiss, Pepper Jack....."
Me: "Swiss"
Then comes the Topping
Me: " Can you put some capsicum"
Subway: "Excuse me!!!"
Me:Capsicum"
Subway : "Sorry, I didn't get that"
Then I have to point out the green pepper.
By this time, I was thinking why did I came here.
Then....
Subway : "Any dressing"
Me : " No thank you"


May be Mangale can script it better.
