I live in a house with other people. Someone else had something sent to them by a family member so neither of us knew it was arriving. He's not in. Postman came to door to drop off. Saw me upstairs and I swear was banging on my door for 5 minutes so hard it sounded like he was going to break in. Rang the door over and over and over banging in-between. He disappeared, I guess delivered neighbours post then came back and banged on my door again, then next again, then back to me again. He even shouted 'i can see you'. I can't leave when I'm in the middle of presenting to people, especially not senior management, presenting extremely sensitive data. It's not a big house so he would've known I'd have heard him. WIBU not to open the door? Was he BU to keep banging aggressively on my door? All round a weird experience.
