We bought a piano for Emma one month ago, and she has played it since then. We always tell her that grandpa and grandma bought that for her. One day, during a driving, she started thinking about her piano.
Emma: grandpa and grandma love me very much because they bought piano for me.
Mom: do you love grandpa and grandma too?
Emma: yes. We should give grandpa and grandma a rose.
Mom: that is a good idea. do you want to use your money from dog bank to buy rose for grandpa and grandma?
Emma: ennn(she is thinking)... we can give them rose from your garden.
Mom: if there is no rose in mom's garden, do you want to use your money to buy?
Emma: ... no
Mom: why not?
Emma: because I want save the money for later. When Mom is old, I need it to buy mom a toy.
