Just got a fright.......

I was happily whiling away the afternoon with my book when suddenly the front door opened, then there was a huge thud and bang and the door slammed shut. I ventured into the hall to discover it was a courier delivery of two large parcels which were now half way down the hall. Fortunately there was nothing breakable and I do appreciate that these couriers get paid a pittance per parcel delivery, but could they at least knock? My heart was in my throat for a good couple of minutes.
