What taxi?

I had a mildly disturbing experience coming home from work today, and the more I think about it the more worrisome it becomes. Like most mildly disturbing experiences in Boston, it was on the MBTA, or rather the bus.

Coming home from Shaw's after work, I saw a bus headed in the other direction. I knew it didn't have to go far before it turned around to go in the direction I was headed, so I stopped at the next bus stop to wait for it, at a four-way intersection. A few minutes later, I see it coming and step off the curb -- traffic was very light. The bus doesn't slow down, so I wave at it, and it comes to a stop in the middle of the intersection. I run up and board, and thank the driver (it wouldn't be the first bus to just blow past some passengers), and the driver says to me "I can't see you when you hide behind the taxi like that."

There was no taxi at the bus stop. There was no taxi on the entire street that I could see. There was a small SUV stopped at the very edge of the "no parking - bus stop" zone, but I was on the opposite edge -- well over an entire bus length away, and you know, standing in the actual street. I assumed that's what the driver meant and pointed out it wasn't a taxi, just some guy parked down the street, and he said "well whatever, you have to make yourself visible."

Apparently I wasn't doing enough to be seen behind a non-existent vehicle. Okay then.
