It's not laziness, it's just bloody difficult being in work mode for such an extended length of time!
I have had one hour bookings that were horrific due to the dynamics being off, and I've had full day and even travel trips that have been awesome. It all depends on dynamics.
I met a guy for a dinner date, which was out first meeting. He drove around 4 hours to get to me. Over emails, and even on our brief phone chat prior, he seemed like someone I'd get on well with. When I met him he was so shy and inexperienced with women it was like pulling teeth trying to get conversation out of him. He asked to extend to an overnight and in theory, I could have. But I declined because it would have been torture.
I don't even like working past 6pm these days because I want to go home, get into my comfies and just relax.
But that is the beauty of the world, we are all different and all like different things!
