I want to tell you something funny story.

I used to visit India for my buisness trip. Actually, it is customary for Indians to answer "No problem" when someone ask about something . It doesn't matter what the questions are. For example, when i went to the local cousine, i found out that there was a cheap and deliciaous looking lobster dish. But it seemed like that nobody try to that item. So I just asked them to order. They said "No problem"..
And i waited for the dish for about 1 hour. But they didn't serve the food. Finally i realized that the chef went to the riverside to grab some lobsters when i was looking at the kitchen.
here is another thing. When i was taking the bus, i felt some unforgettable hand on my hip. Actually at that time, i had relatively long hair. So i thought that this guy misunderstood that i was a girl. So i talked to him in a low voice. "hey i am guy." and It seemed that he was so embrassed for a while and he said a few seconds later...
