<p>If it is a serious issue, you might try writing a note. Then your kid can read it privately and get your message without emotion, shouting, interruptions, etc.</p>
<p>I’ve done many things–as a kid, teenager, young adult, and older adult–that my mom (calmly, reasonably, logically) advised me not to do. Whenever I told my mom that I was going to do X anyway, against her advice, my mom’s closing words were, “You’ll regret that.” She turned out to be right every time! (But she never said, “I told you so!” after the fact. Thanks, Mom.)</p>
