We, your wife's best mates, ask you to come round, which is pretty weird considering you personally never hang out with us... But it's clear very quickly that we weren't inviting you for a friendly cup of tea. Nope, we have some information about you. Some evidence, of something you've been doing, that if we told wifey, would absolutely destroy your relationship. But not to worry... Provided you give in to our demands, your secret's safe with us ;).
