It's just one minute, but it's awesome. Check it out at Shoshana's "other" blog.
The idea of how every little action we do affects what everyone else does is not only perfectly shown, it is so incredibly true. When people see the others around them acting a certain way, that will in turn cause them to act a certain way - for good or for bad. Harking back to the discussions here about New York, it isn't that New Yorkers are necessarily 'bad people' - it's that everything is so rushed here, people are forced to ignore what goes on around them much more, and those little things - the ones that make all the difference - simply don't happen. But that doesn't mean we should stop trying.
