Talking Two Year Old

As Harper's vocabulary continues to grow, I am constantly amazed at the conversations we have.  Here are a few gems:
1. (Background - she loves to close all the doors upstairs every morning.  Also she watches Dora the Explorer as much as I'll let her.)
       Me: Harper, Mommy needs you to open her door
       Harper: No.
       Me: Please open the door.
       Harper: No mommy, you have to say abre (open in Spanish)

2. While making silly faces and noises at lunch....
      Harper:  What's Harper doing?
      Me: I don't know
      Harper:  I don't know either
followed by 2 minutes of hysterical laughing.  Seriously, when did she learn "either" and how to use it correctly?

3.  Harper:  I want to watch T.V.
     Me: Why?
     Harper: Because I have to.
Maybe we need to do some lessons on have to versus want to?!

Some days I think I'm conversing with a 14 year old.  I can only imagine what's to come.
