You know, while it sounds like a really ignorant comment, most people speak from their own experience--if he commented that it was a good way to kill time, chances are he's one of these people who DOES have a lot of time on his hands. While it's a foreign concept to many people who never have enough hours in the day, I see people and know people who are like that, and I think they must be lonely when they pretty much just go to work and then go home and have long evenings and weekends with nothing much going on. I don't know if they lack imagination or drive, or if they have difficulties connecting with people, or are afraid of new things, or if they just value their time alone, but I would tend to feel sorry for someone who makes a comment like this rather than being defensive or critical.
