Answer:
I give people a huge fright, but at the end I'm sweet. I normally celebrate at night, when there's less heat. What am I?
I can be thin but not fat; in your body but never on your placemat. I'm always better when I'm fresh but you'll never see me in the flesh.
Never ahead, ever behind, yet flying swiftly past; for a child, I last forever; for an adult, I'm gone too fast. What am I?
I'm not a bird but I can fly through the sky. I'm not a river but I'm full of water.
