No, LM - not Tescos. If you must know, we had a lovely candle-lit dinner together at Pont de la Tour before strolling along the South Bank, pausing briefly to admire the silent, shadowy bulk of HMS Belfast. It was then that I whispered in her ear "did you know, those big guns on the fore deck are aimed directly at the London Gateway Services on the M1? That's the over 13 miles away!" And do you know what she did? She used her GPS wizardry to simulate the trajectory of the shell, all the way to it's target, just for me.... Wonderful.
