Hadn't been on the bike for a week (house-sitting in AZ for a friend). Get the bike out yesterday morning, the rear tire is a little flat. I'm running late so I quickly pump it to normal.

Must have pumped it too quickly--when I left work yesterday the rear tire was flat, and I can hear each pump-full of air leaking out through the valve stem. Oh well. I change the tire there outside the exit of my building with people walking by. It's funny to me how little people know about bikes. I do appreciate their concern--but asking me if I can change a tire by myself? Uh, yeah, I can handle it.

This morning I had a lady buzz me. I'm taking the entire RTOL, preparing to change to the straight-thru lane because I'm continuing straight. I check shoulder, there's a lady behind me in the RTOL and no one in the stright lane. I signal (arm straight out to the left) and start my move. Suddenly she's in the lane next to me! She passes me, then cuts back over into the RTOL and makes the right turn.

I followed her into her parking lot and arrived just as she got out. She said, "I didn't mean to cut you off!" "So why did you?" I asked. She said, "I didn't know you were going to change lanes."

I held my arm out to the side and said, "What does this signal mean?" She gave me a blank look. "You don't know, do you? Lady, take Driver's Ed," I said, and rode off.
