Losing your keys (inconvenience) is damaging when a thief finds them. Contrary to what the media wants you to believe, thieves make up a very small percentage of the neighborhood.
When someone from the community finds your keys and goes out of their way to get them back to you, your faith in humanity is instantly restored. There are more community members (contributors) than there are thieves.
However, there are more bystanders than thieves and community members combined. The most damaging part of inconvenience is that bystanders sit back and say, “This isn’t my job, that is someone else’s responsibility to take care of this.” To justify this, bystanders will quickly point out, “Maybe they shouldn’t have lost their keys in the first place.”
