WHY??

Do you know how many thousand times a day Andy and I hear the question WHY?? Luke asks why over and over and over. I'm going crazy tonight! I think the "why" quota for today has surpassed it's limit! Here is a sample conversation I had with Luke tonight more than once that went something like this:

Luke: What's this?
Me: Ty's vitamins.
Luke: Why?
Me: Because he needs vitamins to be healthy.
Luke: Why?
Me: He just does.
Luke: Why?
Me: I ignore this one.

If you ignore all of them he just keeps asking! If you simply say "because" he keeps asking! It's great that he is inquisitive and all but oh my gosh! The 'whys' around here are endless!!
