I don't think you should do that!  Stealing is wrong!  If you just want to get the money and leave, I'm sure you could talk with the person first, or negotiate with them.  You don't really have to break in.

Did you know that there's a better way to get money than by breaking in someone's house and stealing it?  I know that stealing isn't nice, but there's a nice way to do it too!  How about if you made some money for yourself in a nice way, by making it, for example, by doing a job?  You could learn a trade, like plumbing, and use your skills to fix the sinks and showers of people who need them, and use the money that you earn for your own good!

This is a good question, because actually you don't really want to break in someone's house!  What exactly do you mean?
