I ended up going downstairs and telling my housemate that I was leaving, and she got up. I brought my poor sick friend a bunch of get-well stuff, and watched him puke a few times, then I went out to the canoe launch and just goofed around and looked at turtles and took pictures, and then I got a call from another friend and went and hung out, and took my smallest daughter to a BBQ, so I had a pretty good day after all.
Plus, I have a line on a cute used kayak for cheap!
