M：Good afternoon, Linda.

W：Good afternoon, Ken. What brings you here?

M：Well, I just sent my car to the garage so I thought I‘d better pop by to say hi，since I‘m in the neighborhood．

W：What happened to your car? Didn‘t you just get it fixed last week?

M：I did But this time it‘s something else. The filter needs to be changed and the brakes keep making squeaky noises, whenever I tap them.

W：I used to have that problem and it worried me every time I stepped on the brakes. I thought I was going to go off the road or something until I took care of it with a few tools

M：I just received an estimate and it‘s going to cost me$200 for parts and labor．I hope that‘s the end of it, because I can‘t afford to have more work done to it again.

W：I guess you must regret buying such a lemon. Didn‘t you buy it three months ago? M：It‘s embarrassing. I was only looking at the exterior and neglected the engine, which should be the priority when it comes to second-hand vehicles.

W：Exactly. But that‘s what you chose at that time.

M：I even thought I had bargained like a pro, since I got it for next to nothing. Now l think maybe I'd have been better off with nothing. What a headache, I tell you!

W：Well, just think of it this way. You paid for your lesson on your car.

M：You are right. But I think it is a costly one and I‘m not going to make the same mistake again. W：Don‘t worry. Perhaps it‘s not as bad as you think. Maybe you just need a little mechanical help from your more mechanically inclined friends--like me.

W：It‘s good to see you back! How was your trip to Canada? You went to the Rockies, didn‘t you? M：Well, word does get around, doesn‘t it? Yeah, it was great. The place has a kind of ―European-Alps village‖ charm to it, but at the same time it has some great day hikes. Want to see some pictures?

W：Sure. I see what you mean the background mountains are quite something. Wait…don‘t tell me you actually went on the cable car ride. That‘s quite a height! I thought you said these things frightened the daylights out of you and … here you are.

M：Yeah, what‘s interesting about this canyon is that it was basically the result of the Ice Age retreat in a small stream eating its way for many years down a valley. That glacier is something else.

W：I still don‘t understand why it doesn‘t melt during the summer. It can‘t be that cold.

M：Well, we are up about 5,500 feet there, but glaciers by nature melt only about a few inches a year. The density of the sheets is the main reason. Besides that, they are protected by a wall of cliffs.
