I read the signs.

To my detriment, I assure you. I had a weird southbound commute situation due to a flat tire. Don't ask. Long story short, when I was trying to get back on the train southbound after picking up the car (again, don't ask), I was greeted first with a train that said 'Los Angeles'. At the stop I was at - Willow Station - the trains often turn around and go back to LA - so in this case, seeing that, I didn't get on. Naturally. Then, two seconds later, the doors closed, and it went south towards Long Beach anyway. There was cursing. (See here for a deeper investigation of my anger at transit and the consequences.) A lot of cursing. I guess pushing a little button to make things easier on those of us who read is too much to ask...
