So..."tough" maybe isn't the right word. But whatever the word, the action will be as follows:

I'm not walking in the morning, because I'm too chicken to subject myself to freezing temps. But I have to walk, for my health.

So...B is going to borrow my car for her errands, and first she's going to drop me off at my local Starbuck's where I am going to buy Kirsten a mug for her birthday.

Then, abandoned, I'm going to walk home. This is my way of jump starting my walking regimen.

Wish me luck!
