My DS’s nickname for me after the 5th time he change my Apple account password ( he was on my account until he was 18) without telling me. He couldn’t remember it. He was on first name terms with the school IT bloke because he forgot his password monthly.
He is bordering on polymath-like knowledge and photographic memory which totally excludes passwords. I blame the mobile phone which cleverly stores and recalls passwords, meaning we no longer have to remember them. I can recall loads of past phone numbers from pre mobile era but I have no idea what my DH or DS’s mobile numbers are.
