Why do I fall for it every time?

Lately, just about every night, Daisy waits until I'm almost asleep and then whines and paces and jumps on the bed like she really has to potty. I tell her no, because I know she just wants to go bark at the deer, but eventually, I give in because I don't want to clean up a mess if she really does have to go out. Then commences the great deer chase, and me standing outside in the cold, yelling and waiting for her to get tired and come back, before I can climb back into my warm bed! Do I bother with the leash? no... that would be way too sensible.

I must really love that dog.
