houses for you and me

since we've been talking about houses in preparation for ada's party, isaac has become aware that not everyone has a house, which was our goal, in part.  he asked me how come not everyone has a house, and i told him that not everyone has enough money to buy a house, and that, in fact, people borrow money for their houses since they are so expensive.  he said he thought we should give some of our money to help someone buy a house.  i was so excited that he wanted to be generous in such a special way.  then he told me "but not my money from my piggy bank."  oh well.  we'll keep trying.  i get it.  it's hard to be generous.  i don't do it well either!
