A: are you ready to go the concert?
M: yes. Shoud we go there by bus so we aren't late?
A: actually, why don't we go there by bike? We could get stuck in traffic if we travel by bus in ruch hour.
M: that's true. Cycling is good for our environment, too. Let me just get my helmet then.
A: is your helmet comfortable?
M:not really, but I liked the design, so I got it.
A: maybe you shoud think about getting a round helmet; they're better.
M: I'll think about it.
A: is that your new bicycle?
M: yes, my father gave it to me for my birthday. Do you like it?
A: it's the newest 10 speed cycling mountain bike. These are really expensive!
M: nothing but the best from my dad. I like everything about it except for the brakes. They are a bit sticky.
A: I can fix those for you. Is there anything else wrong with it?
M: well, my saddle is too low for me. Do you know how to change the height?
A: that's easy. It's important to have the saddle high enough so that your legs can extend fully when you are on your bicycle.
M: is that why my knees have felt sore after every time I've ridden my bike?
A: it's possible. Give me a minute and I can fix these for you and then we can go.
