[speaker001:] What can I do for you, young man?
[speaker002:] I need to rent three pairs of skates for the morning.
[speaker001:] What sizes do you need?
[speaker002:] One pair of 37, and two pairs of 21. One for me, and the other two for two kids.
[speaker001:] Here you are. And here are three crash helmets.
[speaker002:] Thanks. Well, those two kids are beginners. What should I do about their safety?
[speaker001:] Well, there are a lot to do, but nothing to worry about. First, make sure they don't go far from the railings.
[speaker002:] Oh, yeah, maybe I should ask them just to walk along the railings.
[speaker001:] That's a good idea. And remind them to be slow at the beginning, not to run into the railings.
[speaker002:] OK. Anything else?
[speaker001:] Never go to the center of the lake. The ice there is too thin to skate on.
[speaker002:] Got it. Thanks for reminding me. And, are there any intensive training courses?
