Here's a little story for you:
Once upon a time, in Tesco, I came upon the cutest owl pencil case. I picked it up and stroked it and cooed about just how cute it was... and put it down. You see, I had no use for it.
Fast forward to several months later. I had just taken up Zentangle, a sort of meditative doodling type thing, and needed somewhere to store and carry my pens and pencils. Off I went to Tesco, because it was time for the weekly shop, but also on the off chance that the owl pencil case would still be there.
And it was!
And they all lived happily ever after.
