Last legs

I am on my last legs, exhausted, aching, struggling to walk. I won't tell you about my adventure, because that is a rare secret, normally I tell you everything, even the toilet, but today no, all I will tell you is that I am soon boarding the last leg to Wales, and I am very tired and struggling. I will be glad to get there now, a nice shower and an early night would be good if my friends can bear it.
