I just insulted a telemarketer by mistake. How odd.

A week or so ago someone rang my mobile and asked if I was interested in a new handset. No thanks, I said, I don't need one. (But it's free, they said. But I don't need one, I said. They gave me the telephonic equivalent of a very odd look, as if to say ‘who cares whether you need it or not, if it's free you should be jumping at it regardless’, and hung up.)

Today someone rang my mobile and asked if I was interested in a new handset. Hang on, I said, didn't someone ring me about this only last week? Oh, probably, she said, that'd have been a different company, you'll probably get quite a few calls now your contract's coming up for renewal. Fine, I said, then I'll turn my phone off until they go away. OK, thanks, bye.

It was only after I hung up and turned my phone off that I realised that I'd implicitly said ‘… turn my phone off until people like you go away’. She sounded surprisingly polite and amused given I'd just insulted her. Perhaps she hadn't noticed any faster than I had.

When the clocks go forward, every Catholic church in the country presumably suddenly has to hold its services earlier, and of course they are all earlier by the same amount as each other.

Does the clock change, therefore, force equal Mass times acceleration?
