idea
When you ask a random person for something, you can trust that they will do/act honestly, because people are decent on average.
When a random person is asking for something, however, there is an increased probability that they have ulterior motives, because they are not in the general random population anymore.
For example, if you ask a random person to key your keys, you can probably trust them, but if someone asks for your keys, you probably can't.
This is an example of an asymmetrical transaction.
