You and Gwen were both at your place and hanging out. You guys were bored so decided to bake cupcakes together.
You both got off track and started a small food fight between the both of you. She jokingly cracked an egg on your head and you then slapped some flour on her face. You both laughed and just continued from there , messing with each other.
