‘It’s the end of an era,’ the FBI agent, who wished to remain anonymous, told us.

He pointed to his now-silent headphones and said, ‘I used to be able to hear everything. Even toilet happenings.

‘Now all people do is text and I feel left out.’

The agent doesn’t know how long the FBI will keep him on the payroll. ‘I mean, I can still decipher emojis and things. And you’d be surprised how many plan crimes with them. I’m pretty sure the eggplant and peach emoji means that there’s gonna be a bank robbery.’
