Why is it very difficult for the woman to get the time off? [br] [originaltext]

W: The train gets in about six in the morning from Tokyo. I’ll try and meet you at the station but I’m teaching that morning.
M: Don’t worry. I can find my way.
W: The trouble is it’s very difficult for me to get the time off. They’re very short-staffed at the moment.
M: It’s all right. It’s not as though we’re not used to travelling.
W: Anyway, you just get a taxi to the golf course which is where the main road ends. Unfortunately , the taxis don’t like going any further because the roads get pretty rough after that.
M: Ok, we’ll walk if it’s not too far.
W: Yes. Just leave your suitcases at the clubhouse—the man at reception speaks English—and we’ll pick them up later. Anyway, don’t worry. I’ll email you a map showing you the way from there.
M: No problem. It’ll be an adventure.
W: I’ll finish work and leave school at about twelve, so have a rest, maybe take a little walk and get a good look at that incredible view we have of the mountain. It’s fantastic at this time of the year. It’ll be quite safe to walk around. I’ll be back about half past twelve.
M: It sounds wonderful. We’re looking forward to it. Unfortunately Dad’s legs aren’t what they used to be but he can still get about. How long are you going to let us stay?
W: Don’t ask such questions. As long as you like of course. . .
