Twice in the past month I've had that said to me. Both people were blokes. The occupational health guy at work and also the guy who runs the weight loss club I go to.
Easy for them to say but actually if I could take time for me I would because I'm not a fucking moron. And any time they want to take over my parenting duties or to look after my mother or do some of my full time job they are more than welcome. Is this a guy thing? This notion that the world will pick up where you drop things from once you are too tired/bored to persist?
