We all do what we have to in order to survive.
Places like the Valley are too full of people that have no idea how to respond to eye contact and something as simple as 'hi'. Seven day vacation- three winding down, one relaxing...if the kids behave and don't play in the dirt too much, three more winding back up and dreading going back to the "normal stuff".
My 9 year old daughter at the time, wearing a full pack, was violently shoved out of the doorway of a crowded shuttle by a very fat guy that obviously needed to get to Curry before she did. He must have needed a vacation from his vacation. A little more time off might have done him more good and helped his perspective. One big trip-o'- the-year is no substitute for a lot of smaller ones, IMO. We owe it to ourselves and the people around us to keep our priorities straight, but it seems we have a harder and harder time knowing how to do it and why it's important these days.
