Hell, I have come to realise, may not be other people, but repeated, everlasting exposure to 30-second radio adverts featuring one or more of the following:

A voiceover so annoying it creates a Pavlovian resentment – hatred, even – towards the relevant product or company.

A poisonous and moronically simplistic earworm jingle.

A terms and conditions bit at the end which may contain even more words than the actual advert itself.

And sometimes – abandon hope all ye who hear it – you get all three of the above in one cosmically hellish half minute.
