W:Hi,mike,why are you here?
M:Well It's all because of my research paper.I'm just borrowing some books about it.
W:By the way,I want to go to a and b supermarket.Could you tell me how to get there?
M:Yeah,it's pretty far actually,if you're going on foot.
W:Can I take a bus there?
M:Yes,but the bus here doesn't go there directly.You have to take the number 26 bus for five stops And then change to a number 16 bus and get off at the third stop.When you get off,you can see it right across the street from a post office.
W:Oh How inconvenient
M:It is.A taxi would be much more convenient.
