Sometimes the mind suddenly just goes "Kerching!" and your opinion changes. I'm thinking about the moment in Fawlty Towers where Basil is chatting on the phone while angrily asking a guest to sign in. He distractedly asks the guest for a full name and then:
Guest: I'm Lord Melbury, so I usually just write Melbury.
Basil (into phone): Go away! (starts simpering to Lord Melbury)
There's a "Kerching!" moment if ever you needed an example.
