hey dad, next time if the door is closing don’t pull your arm back in. let the door close on it and the conductor will open the doors again. the door won’t sever your arm, big guy.

You shouldn’t bet your life or limbs on automatic doors working the way they’re supposed to.

I know a woman who had both wrists fractured by malfunctioning elevator doors.

No kidding. I used to ride this train (it's called MAX it's not a subway) with my little kids when they were this age. There were a couple of times when this almost happened, and I just forced the doors open with my hand.

This dad let go of his kid and pulled his arm back into the train.

I'd rather have my arm cut off than face my wife after losing my child on a train platform. What if that woman hadn't have been there?
