That would be logical but...

I was just helping D online accessing a games site that he had used previously. He had forgotten his password and wanted to request an email for a reminder. But no matter how many times he tried to input his email address, it was always rejected. He asked me for help (that's a first as they usually go to their Dad with anything techy or monetary!). Anyway, I watched him go through the process again. 'But D,' I said, 'You've put in an extra letter after the '@' sign.' 'No, Mum,' he said. 'It's 'at' - so I put '@ t' just like everyone always says!' We had a chuckle....
