Loves of my son
My son used to love batteries! Yes, you read it right! Well, he could play it as it is or because he needed it for his battery operated toys. He passed that stage already.
We still buy batteries, of course. It is a regular in the grocery list. Well, you use it for remote controls, wall clocks, and even mobile phones.
What is my son up to, right now? So many things! He is fixated with ants, vampires, zombies, caterpillars, and science in general. The wonder of internet!
