&gt; <i>My partner often quizzes me on things that were apparently &quot;discussed&quot; which I actually didn&#x27;t hear because I was engrossed in something else.</i><p>I absolutely <i>hate</i> that. I have a pretty good memory, I do remember lot of random trivias about conversations. And yet my SO can <i>always</i> find something that I missed, and likes to ask me about it few weeks after it was first spoken. I try to convince her to find another way of &quot;checking&quot; my attention, because this won&#x27;t &quot;fix&quot; my memory. It&#x27;ll only make me paranoid.<p>EDIT:<p>Another thing that I actually learned for her is the color of her eyes. I&#x27;m not indifferent. I simply don&#x27;t notice. Maybe it&#x27;s because of being myopic for most of my life, or maybe because I&#x27;m wired differently - but my brain just doesn&#x27;t register those details unless I explicitly focus on them. Similarly, I often can&#x27;t tell when someone brightened or darkened their hair (that is, unless it&#x27;s something like going from blond to black). I suck at remembering faces, couldn&#x27;t describe them from memory to save my life, and usually I even quickly forget what clothes someone is wearing. So my only countertip to this article is - for the love of $DEITY, don&#x27;t assume everyone is sensitive to minor appearance changes. For some, it doesn&#x27;t register. And it&#x27;s not because of indifference.
