What am I doing? I'm warming up food. "Warm up" is an important English phrasal verb.
What did I warm up? Well, I have leftovers from last night's dinner. Leftover is
another key English word. It means the food from a meal we previously ate and
we're eating it the next day again. So these are leftovers from last night's
dinner. So let's warm these up a little bit longer. They're still a little bit
cool. So I'm gonna put it in the microwave and warm it up some more.
