I would say the author uses irony in this passage that remembering his mother makes him not happy but miserable which may be the opposite of what is expected but he would rather suffer this than be happy in forgetting her as this latter feeling would be expected to make him sad.
I believe, 'Now, a day doesn't go by when Mick doesn't join us in the yard.' is the answer.
D. Hook. It is relevant to trying to 'hook' or reel in your reader for a great catch. ;)
An example:
<em>The creak grew louder. I whipped around and out of the corner of my eye, a shadow danced. I twisted back. I heard padding feet behind me. Desperate, I turned in circles as laughing began.....</em><em> </em>would that be captivating? Or what about:
<em>Yesterday was ok. We went to get ice cream. I got stawberry. But it fell on the ground. </em> Wouldn't you want to immediatly put THAT book down?
