Df is Turing 70 and I'm at a complete loss as to what to buy him. He is well off, has everything he wants and doesn't have any hobbies but prefers to work. I thought of paying my mum and dad plus me and my children to see a musical. Shrek is touring near us but just wondered if this would be a naff present ? Thoughts please as I'm worried people will think this is a funny present.
