The Potty Referee

I have a new title around the house, I have dubbed myself "The Potty Referee".
How does one become a Potty Referee, you ask? Well, there's an extensive 4 year training program, continuing education courses... oh wait, I'm sorry... that's how I became a CPA.
Here's the real story...
Anyone who has been to our house knows that there are 2 restrooms downstairs, the full bath between Cackie's room and the spare bedroom (very convenient for little girls to fill up cups of water, take them in Cackie's room and throw them at each other... oops, sorry that's totally a different story/nightmare) and the half bath/laundry off the area that my Dad has dubbed "the concourse".
Well, here recently Cackie has started referring to the half bath as "Daddy's Potty", we guess because he is sometimes in there when she wakes up in the morning. She has become fascinated with using "Daddy's Potty" and will often opt to go in there over using the one attached to her bathroom. (exciting, huh?)
So, tonight we're trying to get her to go to bed and we ask her one last time to go potty. She got out of her bed and took off before we realized that she was not in her bathroom. Michael called out for her and she yells back "I'm here in your potty, Daddy." I headed toward the half bath to check on her when I hear Michael say "well, I'm going to use your potty then". As he said this, the look on Cackie's face was a cross between "how dare you" and "oh, no, what have I done".
So, my response was... "well, you're using his potty... it's only fair that he uses yours". This was followed by the usual toddler arguing and I feel into the trap of trying to defend my husband using the potty in his daughter's bathroom rather than waiting.
Thus, the title "Potty Referee". I can just see my uniform now. (why is that guy smiling????)When I start hearing "Hey ref, you suck" from the fans in the stands, I shall resign my post.

So, just after I had written this, but before I hit post.....
Cackie has gotten into a habit of calling us back into her room just a few minutes after good night kisses and lights out. We hear her calling on the monitor "Daaaaaddddddyyyyy, come here". Michael responds "Why?" Then, you hear this sweet little voice "because I love you" (this kid has never played fair!)
So, he goes into her room... gives her more kisses... tells her goodnight again... and then I hear (in an irritated voice) "Daddy, you used my potty"
Sorry Cackie, I've already refereed one match tonight... that's my limit!
