Mike is really excited about the prospect of being shrunken in the city. Maybe he can spy on people, or even climb onto their shoes and go home with them, and no one would even know. At least as long as he was careful.
So Mike finds himself standing on the train platform with an interesting question: how do you shrink yourself without being noticed? He has two ideas at first, neither very good. One idea is that he can wait until the train arrives and hope no one notices him shrink while everyone crowds on. Basically, if he shrinks in a crowd, hopefully no one will notice and he’ll have shoes all around him to hop onto. As a safer alternative, he can just find an isolated part of the station platform, shrink himself there, and then wait for someone to come along and try to hop on then.
Unfortunately, there are downsides to both plans. Mike’s not too eager to shrink himself for the first time in a crowd, where he’ll have to act almost immediately to avoid getting stepped on. The other plan is less dangerous, but he’s not sure there's any isolated place on the platform where he can shrink and still be confident that no one saw him. But he really wants to hang around on the train shrunken. What would be a better idea?
