I just had quite an unnerving experience – I work from home and am at home on my own. Eating lunch downstairs and all of a sudden my dog starts going crazy and I hear the front door opening. It turns out a delivery driver decided to let himself through our front gate without ringing the bell (which is really obvious) and open our front door without knocking to deliver a parcel... I've never had this happen before and am really shaken up by it. I normally have the front door locked when I'm home alone but had been going in and out and obviously didn't lock it when I came back in with stuff in my arms last. Why on earth would a delivery driver come into someone's house uninvited?! Why not just leave the parcel outside the front door or the front gate (as is often done)? He then kept trying to take photos of the parcel as I was asking him to leave and obviously quite upset. Am I over reacting or is this really out of line?
