So, if you have so little contact, how have you managed to gain access to his account? I doubt you know his passwords, or went out of your way to log-in as him, which means you're sharing a computer. In any which case, you've been in close contact recently so why does he need to do any of the above? That's like me texting a flatmate in the next room or poking them on facebook when they're sat right next to me.
