I’ve noticed how grumpy I can get when shopping - especially in the supermarket.

I approach it as a military operation: I decide my menu for the week, write the list to reflect this, then write it in order of the goods in the local store.  I could whizz round and have it done in fifteen minutes.

But there are a few things that get in the way:  firstly, the family - they are always looking at things that aren’t on the list; secondly, other shoppers - they get in the way, stopping to chatter and letting their trolleys block the aisles; and thirdly, me! - yes that’s right - I distract myself, I just can’t help it.  That’s the trouble with all these places - all that temptation.

But it does make me grumpy.  Maybe if I shopped on my own and there were no other people in the shop then I’d stay focused and just get on with it - but there again, maybe I wouldn’t…
