More Money

Lucas is into his money mood again. He needed another 50 dollars to round up his collection. So, today he came to me and asked:

Lucas: Can you give me 50 dollars?
Me: NO!
Lucas: Why?
Me: You have to work to earn it.
Lucas: What can I do?
Me: If you wash my car, I give you 5 dollars. If you sweep the dried leaves from the garden, I'll give you 5 dollars.
Lucas: What can I do that is not a job?
Me: If you sleep in your own room for a week, I'll give you 5 dollars.
Lucas: If I clean the whole house, how much will you give me?
Me: 10 dollars.
Lucas: That's not fair. I have to work 16 hours to get 10 dollars!


Another conversation while I was drying his hair,

Me: Lucas, let's put the money from your wallet in the bank.
Lucas: No.
Me: Why? You can get interest if you put the money in the bank.
Lucas: What is interest?
Me: The bank will give you extra money for keeping the money in the bank.
Lucas: I know, if I put 1000, the bank will give me 5 dollars a year.
Me: That's right. If you put for 10 years, you will get 50 dollars.
Lucas: No, that would be so boring. I can't see my money for a long time.

What can I make up of him and money??
