Circle of life

Spring is here. Ankit sees new plants coming up in the backyard and asks Mummy about them.

Ankit: Mummy, where do seeds come from?
Mummy: Flowers
Ankit: And flowers come from plants.
Mummy: Right
Ankit: And plants come from seeds.
Mummy (wondering where this all is going) : Right..
Ankit: So where do seeds come from?
Mummy: Ankit, this is called circle of life. Seeds come from flowers, flowers come from plants and plants come from seeds. That forms a circle.
Ankit: Do human beings also have a circle of life?
Mummy: Yes they do..
Ankit: How?
Mummy: Where did you come from?
Ankit: Papa and Mummy.
Mummy: And where did Papa and Mummy come from?
Ankit: Their Papa and Mummy.
Mummy: Right, so you see there is another circle of life.
Ankit: No, that is not a circle.. that is just a line!
