Potatoes & Knitting

I think I smell of mashed potatoes...

Or at least my jumper does. Not entirely sure why. I haven't been anywhere near mashed potatoes since Christmas day.

Also on today's list of musings - is there a word for people that collect non-fiction books but don't actually read or use them? 

I think I'm becoming one such person. The actual purchasing of a book, for me, especially non-fiction books, has now become more about the marginal intention of doing something that's related to the contents of the book rather than the actual reading. I think I like the idea of becoming or mastering whatever the topic is, but completely ignore the fact that I have to actually learn and practice the new craft, almost as if buying the book will somehow magically install the new knowledge and skill directly into my brain like a computer program. Despite the logic of this, I am now the owner of a book entitled:

"You will be able to knit by the end of this book". 

This is concerning for a few reasons:
Firstly, I don't think I have the financial resources to continue to purchase the rather important yarn to begin such a hobby, should I actually set about it. 
Secondly, when would I actually do said knitting? It's not like I am free of time-consuming vocation and parental responsibilities.  
Lastly, why do I feel the need to knit? Is this just something that comes to people over forty, like the compulsion to collect cats (I have three of these by the way)? 

Remember to:

Put brick on top of paper bin to stop last two weeks worth of copies of the Guardian, parish magazine and random cardboard sleeves from microwave meals being blown into next doors garden.
