Let me just explain what's happened. It's been half-term. I've been off plan. I've eaten lots of cake. And other things. And I don't feel guilty!    I have enjoyed every bite as it has usually accompanied catching up with friends. That alone is worth it.    Never fear, I shall be back on it come  Monday morning . I will have four whole days to make amends.    So when I'm asked "Do you know why?", I shall answer "Yes! Because this time, it's got to work for me. If that means taking time out when I'm on holiday, then that means that. Doesn't mean I don't start again."   Six weeks until Easter!
