Notes:

a. The use of words like 1 and 2 makes Nepali sound like Nepali so I have added two more.  May be we don't want to be precise about time, money and so on so we love saying them in round figure.

b. The Nepali word for Office is adDa, which is not used in eveyday Nepali though. 

c. Nice use of dai and bhai.
