Got an email from a manager in another office to email a form to a customer, which i did, manager then phoned to tell me I had sent the email to him instead of the intended receipient. Without checking the first email I sent, I assumed I had hit reply instead of forward so i sent it again. Two minutes later another phone call "you've sent it to me again". Upon checking both emails, I sent both to the right person and had cc'd the manager into both so he could see it was done. Turns out he just doesn't understand that he can be cc'd into emails. "Why is it in my inbox if you sent it to the customer".
