It's a nice sentiment -- except for the guy sticking his foot in the subway train door to hold it. The TTC has begged people for ever to not prevent the doors from closing, as they say this can cause mechanical problems on the train, and make delays for everyone.
So, by all means, share the warmth this year, and help out, but as far as the subway goes, you do more people favours by letting those not on the train catch the next one.
Happy holidays everyone!
