Hhm that sounds like the type that go to a gig or festy and have an amazing idea/s when the band are playing but are completely bereft of their own entertainment when there's nothing on.
Are talking about zany people Turk's?
Building sites, decent pubs and football tend to scare these gifted individuals away. I am back in a position to go to more games, earning more and wife has left me. Thing is I'm not really in the mood for zany.
