I Lied About Reading the Memo

Today at work, I got an email with some new rules about lunch breaks. The boss said if we didn't follow them, there'd be consequences. So when she asked who read it, my hand shot up. But here's the thing, I didn't even open the email. It was just too boring. Now, every time someone mentions the memo, I get all jittery. What kind of colleague lies about reading something so small? It feels like a big deal in my head.
