Wait Don't Tell Me ..... It'll Come Back To Me Soon

Someone says hello to you. Someone whose name you should know. Someone whose name YOU DO know!! But suddenly you draw a absolute blank. You laugh and pretend that you're having a senior moment but you are legitimately struggling to remember. Finally after 30-45 excruciating and frustrating seconds, it comes back to you. It's a relief of sorts. And the person walked away laughing. But you stand there wondering how such a thing just happened? You write it off to the craziness of work swirling about at that given moment but can't help but wonder if that's the true excuse.
