Question: Person1: Sam , I am so sorry . It was your birthday yesterday and I completely forgot about it .
Person2: Don't worry about it . I keep forgetting everyone's birthdays as well .
Person1: Margaret really told me off when she found out that I had forgotten all about it . We did try to phone you , but you and Jane must have gone out .
Person2: Yes , Jane invited me for dinner to this new restaurant which opened near us .
Person1: Oh , yes , I know the one . How was the food ?
Person2: The food was excellent , but Jane ordered a birthday cake , which they forgot about . So as you can see , you were not the only one .
Person1: Oh , no .
Person2: Yes , Jane was quite upset about it . The manager came to apologize and we did get free dessert , but still ...
Person1: I would think this was the least they could do .
Person2: In the end it was a nice evening and I got an iPad as my birthday present which I wanted for a while .
Person1: Great . I have also been thinking of getting one . Do you think you could ask Jane to have a quiet word with Margaret ? My birthday is not that far away .
Person2: I can try , but knowing Margaret she will see through that immediately .

Question: Person1: Well , Mike , nowadays there's much talk about nanometer . But what on earth is it ?
Person2: Nanometer is a length scale . It's one billionth of a meter , roughly ten times the size of an individual atom .
Person1: Hmm ... it's hard to figure out the exact size , I'm afraid .
Person2: Well , let's make it this way . For comparison , 10 NM is 1000 times smaller than the diameter of a human hair . There are as many nanometers in an inch as there are inches in 400 miles .
Person1: I see.Thank you .
