You know how a dog will cock his head to the side? I don’t know if this is true or not, but, when that happens, I see curiosity. Same with my cockatiel friend here. Head cocked = curiosity.
It’s a reminder to me that, when questioning something, or seeing something for the first time, sometimes it helps to pause and look at it in a different way.
Even if that just means cocking my head to the side.
