A yellow tail

Last night you were so tired that you were just unreasonable.. and I was pretty tired too so I just went to bed WITH  you... So, we are laying there and I'm almost asleep and you are desperately trying to stay awake and then I hear you say to yourself ...

"I don't have a tail.  Skyylar has a tail.  Lexi has a tail.  I don't have a tail.  I don't have one. I need to go to the store and buy one.  I need to buy a tail.  I will buy a yellow tail. I like yellow.  yellow is my favorite color.  I will buy a yellow tail at the store..." and so on until I finally in between tears of laughter I say to you "Javan, you can't buy a tail at the store.  People don't HAVE tails" I think you were surprised to hear me because I think you thought I was asleep and now hearing the laughter in my voice you just BUST OUT laughing... and you put your forhead to mine and we just laughed and laughed together.
