Hello my darling.
In the last week or so it seems that you have made a fundamental change in your exploration of our world.
For the longest time you have been meticulously cataloging the tangible objects you have come in contact with.
“What’s that?”
“A chair.”
“What’s that?”
“Snow!”
You now seem to have a good grasp on the fundamental elements that make up your usual stomping grounds so the question of the days most recent and those to come is “Why?”
I’ve been very excited about this phase of your development since well before you existed. In fact, well before your mother and I even met. I have always wanted to answer the million inquiries that help shape a child’s understanding and view of the world.
I look forward to seeing your quest for knowledge grow more complex, and I promise that as you dig deeper with your questions I will do my best to answer every subsequent level of “Why?”
A conversation from yesterday at dinner.
Me: “It’s time to get cleaned up and get ready for bed!”
You: “Why?”
Me: “Because dinner time is over, and now it’s bed time.”
You: “Why?”
Me: “Because bed time comes after dinner time and it starting to get late so that means it bed time.”
You: “Why?”
Me: “Because time is generally perceived to flow in a linear progression with later events like bed time following the earlier events such as dinner.”
You: “Oh.”
Me: “Are you ready for bed?”
You: “Yes!”
Glad we got that sorted out. 
I do hope you never stop asking why. Feel free to challenge me; if I don’t know the answer we will go find it together. If we have to perform an experiment to find the answer, I’ll be your willing lab assistant. If we just plain can’t figure it out, well, there’s always a million more questions to consider while we let the stumper ferment in our minds. Feel free to call me when you figure it out, any time of the day.
