Write a paragraph or a short story using the words frugal,discreet,imaginary,prom… and instead.?

The other day I was shopping downtown with my imaginary friend Margaret. We have a lot of fun together, but she is quite frugal, which is awkward when I want to buy something extravagant. Take my prom, for example. Margaret and I had to find dresses to wear so we could be beautiful, but instead of going to the department store everyone else goes to, Margaret demanded we go to a thrift store. After an hour or so, I decided I needed to get out of there before all the good dresses at the other shops were gone. Discreet as can be, I slipped out of the dressing room and ran.
