used the automatic doorbell to catch the delivery driver. Although this one actually managed to jam the package through the letterbox anyway rather than posting a card pretending I was out.

was confused by your doorbell, as the sound was delayed and nothing like a bell. It told me it was on its way.

a normal doorbell (only usable by competent people and which isn't very loud), an automatic intruder-detecting doorbell (which generates lots of false positives and always rings twice but wasn't in operation for you) plus a hypersensitive shouty person on alert.

if the middle one is a postman.

put the automatic intruder-detector doorbell back on because the delivery of the order had got split into 2 lots.

was only just in time because this delivery person was even speedier - but also had a smaller package which fit very easily through the letterbox anyway.
