From a catalog that we recently received, Kiddo discovered two things that she really, really wants. One is a blow-up water slide/pool for the backyard. One is a play house. Both cost over $500. They are too expensive for our life right now. And we told Kiddo this over and over (then finally hid the catalog). There has been a lot of weeping and wailing, and truthfully she is still sad about it.
Today we were looking at the housing classifieds, and she pointed out some houses we could think about buying. The ones she was looking at cost over a million dollars, also too expensive for us. And I told her that.
"People who say 'yes' to expensive things can live there," she observed sadly.
