Thankyou all - was whisked away Friday afternoon and spent the weekend at my Brother's in East Finchley with sister and her other half. Not used to two days on the lash nowadays so definitely feeling my age today!! Popped into Fortnum's this afternnon and managed to get a tea which will infuse well at high altitudes (water doesn't boil at 100 degrees in Lesotho) think I've got enough to last me the trip as long as I ration myself - cost me a fortune!!
