Thanks guys for all your kind words and messages of support. My Dad passed away last Thursday, the funeral was on Monday. In the space of just three weeks he went from fit and healthy to no longer with us. I'll miss him but I'm coming to terms with it. It will take a day or two for me to get back to being my usual cheerful self but my father would have been the first to say life goes on. I am most grateful to all of you who took the time to reply. Thanks again!
