Aggrivation!!!

So I have been going on walks about every other day to get some exercise. Today was a great day. I walked down to the BX which at first was talking me about 30 minutes to get there. Today it only took 25 minutes! WOO-HOO! So I go in, I walk around and pick up a few things, a couple pairs of shorts, shampoo for Blake and a movie. I take my time while I'm there since its still "MY TIME".
So any who, I'm getting hungry so I go grab a bite to eat and then head home. About 25-30 minutes later I'm home and come in to greet my animals. Pepsi comes running meowing at me. Lexi is no where to be found. I walk around the kitchen and back into the living room where she is now poking her head out of the hallway with her ears down. I'm thinking great...she has done something wrong. but what??? There is not evident sign that she has done something wrong so I call her and she runs off to the bedroom and lays on her bed. I call her out and she eventually comes out. I call her to the living room, still ducking her head she slowly comes out with her tail between her legs. I walk into the kitchen and call her and she slooooowwwly comes into the kitchen.
I get to the pantry and she does not come to me at all. I figure she was getting into the pantry. When I tried to get her to come over to me so I can smack her nose for it...SHE PEEEEEEES!!! OH MY GOSH! She i knock her over with my foot to get her to stop peeing and she runs off to the bedroom again with trails of pee following her! Holy crap! Now not only do I feel the need to beat her but now I have to clean up this pee trailing around my house! AAARRGH. Not the way i wanted to end my wonderful walk...cleaning dog pee. **sigh**
