The "Whys" Have Begun

It's official, we will now be answering "Why" questions multiple times a day for many, many days. Here's are a few recent conversations with Connor:

C: Why to the girls have to go to sleep?
Me: Because they are tired and need a nap.
C: Why do they need a nap?
Me: When people get sleepy, they need to take a little nap. It helps them grow big and strong.
C: Why do people grow big and strong?
Me: I guess that's just how the universe works.
C: How does the universe work?
Me: (Silence...I am already out of answers.)

C: Where are we going?
Me: We are going to the store.
C: Why?
Me: Because we have to get a few groceries we need.
C: Why do we need groceries?
Me: So we can have food to eat.
C: Why do we eat food?
Me: We eat food when we are hungry.
C: Why are we hungry?
Me: We get hungry when we need food to help us grow big and strong.
C: Why do we grow big and strong?
Me: (*Sigh*...I know where this is headed) That is just the way the Universe works.
C: How does the Universe work?
Me: (Silence...again we are at the end of the road.)

Lastly, one with Connor's Dad:
C: What does "sticky" mean?
Casey: It is like when you get something on your arm and you touch it and your fingers make the sound "CHH, CHH" (demonstrating & referencing a recent sap-on-Connor's-arm-incident)
C: What does "CHH, CHH" mean?
