### Comment:
Think of it like this. 
  
 The soil is fertile, you think it'll grow great jumbo watermelons. So you barter 10 lemons for this watermelon field. But it turns out the field is only good for growing little watermelons. Still grows watermelons, but now no one will offer you more than 5 lemons for the field.

### REPLY:
Much better, thank you. Though the lemons are still throwing me off a bit, I think I get it.
