People
Things we are glad that are gone: traffic, rush hour, crowds, filling your gas tank regularly, waiting for the subway, shuttling your kids to and from places.
There are things we miss: passing strangers on the street and nodding hello, the bright smile of a friend who bumps into you randomly at a restaurant, that waiter who knows you and greets you by name, the guy at the dry cleaner who asks about your kids.
As we move forward and the world slowly (please) loosens up, add more people and less hustle and bustle.
