K	:	I think weʼre lost.  I canʼt find the history museum.
S	:	How about asking that lady?
K	:	Good idea.  Excuse me, maʼam?  Could you help us?
W	:	Sure, whatʼs the problem?
K	:	Weʼre looking for the history museum.
W	:	Thatʼs quite far from here.  Walk down this street for about 30 minutes.
S	:	Can we get there by bus?
W	:	Yes.  See that sign over there?  Thatʼs a bus stop.
K	:	Thank you very much!
