In my car, I always check the windows (darn that sunroof, though, sometimes I forget it ), regardless of who my passengers were, or I'll ask whoever it was to roll the window up. With power windows and having control over them at my seat, it's just as easy for me to roll them all up myself.

If I were upset with anyone in the situation you describe, Libby, it would be myself for not checking. Some people leave their windows open during the day to keep the car cooler. Maybe that's what your friend was thinking. Anyway, the only thing I would have done differently is never said anything to him about it. We live and learn about those situations, though, I guess.

But to answer your original question, yes I always try to remember to roll the window up when I'm riding with someone else!
