“Penguins walk in a straight line,” my son declared. The picture speaks for itself.

It seems that the visit to Bird Paradise has created an indelible impact on him. Time well spent!

“So do ants. They walk in a straight line,” I remarked, eager to add on to his pool of knowledge.

*Upon consulting Google, I belatedly realised that I should have used *walk in single file* instead, but oh well, I will correct him and sharpen his understanding in due time.* For now, I was basking in the satisfaction derived from his application.

“Did you know that light travels in a straight line?” I elaborated. Ya, I’m a 举一反三 (learn one example, infer three others) kinda guy.

I look forward to having my mind work flexibly and nimbly as my son understands the big bad world more.
