Tonight, the oven that Dad bought online finally arrived, and our whole family was so happy. Dad said he would bake sweet potatoes for me, so we washed them together and put them in the oven. Dad turned on the power and turned the knob. After 50 minutes, the room smells good. Dad took out the sweet potato, let it dry for a while, and then I began to eat. It's delicious. I love dad.
