Month of Thankfulness-Day 8

I am thankful for football.

Football:

-brings an extra sparkle into my little man's eyes.

-gives me a reason to purchase cute stocking hats.

-is a definite connection point for the men in my life.

-is a fall staple. 

-is a perfect excuse to drink hot chocolate while snuggled up in a cozy quilt with this sweetie.

-is a constant conversation topic with Andrew.

-is a sport that I am struggling to fully understand.

-is going to be an integral part of the rest of my life.  My kiddo loves it...therefore, I will love it too!

So...What is an interception?  Exactly what does the tight end do?  Is there a yellow flag?
