Failure! Failure! Failure!

I didn't run today. I got up early enough, but long story short couldn't leave my daughter by herself which would have happened had I run. In fact, I didn't do anything right today. I ran around like a maniac on my first day back to work, grabbed fast food along the way (while my daughter reminded me how bad it was for me), ate some ice cream and even had some cake with my wine this evening. I'm not giving up despite my failing grade, however. My neighbor has told me we're running on Friday morning whether I like it or not. She's decided I'm not going to like her for at least 2 weeks (and the more she talks about it the more I believe her.) To get ready for Friday, she's told me to drink lots of water tomorrow and load up on carbs for dinner -- the multi-grain-type. I'm getting scared. What if I collapse? What if I lose my friend because I just can't run?! (this coming from the person who was always in last place during those "wonderful" Presidential fitness expeditions). Please, leave me with some encouraging words. I'm going to need it.
