Transportation Issues

My car is sick, poor thing. Apparently the regulator for the motor that raises and lowers the window on the rear passenger side has failed.
And I need a new one.
Which is fine, except they're keeping my car for 3 days, 3! DAYS! to diagnose the problem (yesterday), order the part (today) and install it (tomorrow).
This puts a tiny crimp in our regular, tightly, down-to-the-second, don't-forget-the-last-minute-detail, scheduled days that Tarzan and I have worked 12 years to perfect.
He's on his bike for school since it's a mere 3 miles from home to there. And I have his car for the 15miles is it for me. As neither the bus nor train go to the neighborhoods where I work that is not a viable option. (I've thought it was a bit stupid of the neighborhood councils. All their 'help' come via public transportation. How do they get up and down the hill?)
Here's hoping this doesn't happen too often. We live in a car dependant city.

This is me and have just the one vehicle for a bit.
