Here is an amusing conversation I had with my younger daughter. She is 4 and now she has a lot of ideas and very curious about the things around her.
One day, she had a fever. When I was giving her the Paracetamol syrup, she accidentally touched at the side of the fridge in the kitchen. So she said, "Mama, I think the fridge is also having a fever like me". I was baffled by her statement. I said her, "How do you know?". She asked me to put my hand at the side of the fridge and feel it. Then only I realized and understood why she said that. She continued, "Mama, give this (paracetamol syrup) to the fridge too". She was smiling when she said that because she knew that she was only joking. I explained to her why the fridge is hot but she didn't really pay attention to my explanation because she actually knew that the "fridge doesn't really have a fever'.
