when a person notices an item of theirs missing and finds it in another persons possession. upon finding their item(s) they will see that it was obvious that that person was going to take it without giving it back. that is when the owner of the taken item(s) realises that the other person owns an item that they like, that's equal or lesser in value to the item that was taken. this swap basically remains unspoken of by the two parties involved. in the end everyone should be happy, they both get something new that they both like.
