Is this what it is to get old? Follow the sequence :- 1) Eat too many lentils for lunch 2) Suffer indegestion all afternoon 3) Go to Tesco Metro to buy some rennies to asuage said indigestion 4) Queue up 5) Fumble in pocket looking for change 6) Discover packet of rennies in pocket 7) Remember you bought some at lunchtime 8) Repalce second packet. 9) Creep from store wondering if they're going to accuse you of shoplifting the original packet.

Like, DUHHH.

On the plus side my back is a lot better today!
