It's a trend you can't avoid. Non-children have been reaching to the colouring pencils and markers faster than you can say 'New Popular Mindfulness Trend.' And yes, I did just call them 'non-children'.
I'm not usually one for jumping onto bandwagons. Unless of course the bandwagon will make me more Hipster. I've always wanted to be a Hipster...
So, seen as colouring in is actually something I do really enjoy, I'm delighted that it's now become fashionable for grown-up non-children to do it. They have even invented 'Adult Colouring Books' so that you won't feel embarrassed carrying around an A-4, Disney Princess, clearly marked for kids book. And of course, they can charge you so much more for stylish adult colouring books.
