“it's a stranger and you don't really bear much cost for them you know thinking you did a bad job or you may not really value or care that much about their opinion compare that to the example i gave you know earlier which is you walk outside and your neighbor sees that your lawn is very sloppy and you haven't mowed the grass in three weeks that actually you may care pretty deeply about because you don't want to be judged by the other people in the neighborhood”
