Frazzled

For some reason I feel rather grumpy today. I shan't bore you with details, but here's one thing that grumped me today ( and if grumped isn't a word, then it ought to be ).
Thinking maybe I was dehydrated a bit and that was making me snappy ( nope ), I bought a 750ml bottle of water. I got it in a cut-price chemist chain shop and it cost 39p.
Now if they can sell it for that much, and presumably make some sort of profit, why is it so much dearer everywhere else ? Just sayin'.
Anyway, music hath charms and a little bit of Van the man works wonders. The harmonica and saxophone are luscious.
