I wish I could be honest with you. That night at M’s party became a pretty singular mistake. Just like the mistakes I made later, only this one didn’t affect you. This one didn’t make you bring someone else home and then lie about it, but I suppose you didn’t know me then, you didn’t know just how easily I can tell when someone is lying. It’s a strange ability, one that leaves me very unhappy. You should know that there aren’t any positives to knowing when someone is lying, except perhaps when you’ve caught them in a lie that benefits you, such as lying about your surprise birthday party. But cheating isn’t a surprise birthday party.
