To share or not to share

<p>My mother makes a wonderful pie that’s always a hit with just about everyone. She found the recipe in a cookbook 40 years ago, made some modifications, and has been serving it on special occasions ever since. </p>

<p>People ask her for the recipe all the time, but she gives them the original recipe and doesn’t mention her modifications. She’s normally a very kind and generous person, so I’m not sure why she does that. (I suspect it’s because she’s a fairly average cook and gets a kick out of having at least one thing that she does better than everyone else.)</p>

<p>Hey, at least she gave <em>me</em> the real recipe!</p>
