Conclusion.

I have a cocktail napkin on my desk with a phone number written in black sharpie. There is no name. I remember writing down this number, but I have no idea who relayed it to me.

I seem to be forgetting my size. I keep banging my knees on things. I used to be much better at knowing my physical boundaries.

I now run errands. When I was little, my mother always seemed to be running errands.

Looking at these three above points together for the first time, I'm thinking they are all age related.
