Stupid stupid stupid

Having been avidly tracking my parcel (burgundy ankle boots) I was expecting it to arrive this morning. By afternoon, with nothing showing up, I examined the tracking details again. Delivered. Well where were they? The gate makes a noise, and it hadn't. The hiding places were all EMPTY of parcels. I tried to phone the mail depot and listened to 20 minutes of Covid excuses, getting more and more stressed because nobody real was (awfully bad language, getting fouler by the second) answering. The Lord and master came in eventually and asked me why I was stomping around in such a snit, so I explained.
Yeah, he said, they came this morning. I put the parcel on the dining room table.
Why would anyone sane expect me to look for a parcel on the dining room table? Why? Why? Why?
