Seeds, growing and friends

Jason: How did the first seed get here on Earth?
Me: Seeds are inside of fruit, berries, flowers and other things. It's part of nature - the seeds grow with the fruit or berries, and when they fall off and it rains they get buried in the ground and grow more fruit or berries.
Jason [growing impatient]: But how did the first fruit or berry grow - it had to have seeds to grow from?

Sydney: How do friends become friends?
Me: Why don't you tell me? How did you make all of the friends that you have?
Sydney: First you meet them, then you introduce yourself, then you say: "Do you want to be my friend?" Then you play nicely.
