stand up and show us your funny face

i want my first painting in my art class to be a big ol' hamburger with curly fries that i took a foto of on new year's eave. (i know: sp.)
but i feel uncertain that i can justify this if she says to me something critical about my subject matter. so i was thinking of what hamburgers mean to me and why would i want to paint one and what would i do with the painting once it is finished?

or i could be boring and paint these sunflowers.

i don't like it when people are always in my business. i need my PRIVACY man!
