A Lie at Work...

I was working as the barista when my ex called me while I was on break. We'd been together for a year and broke up a month ago, but things were still awkward between us. He asked if I had any plans for Saturday night, wanting to meet up. But it was already set... My best friend was coming into town that weekend for our weekly date night ritual, which he didn't know about. I fibbed and said I was busy with work stuff, feeling guilty but also relieved at the lie protecting my little secret. It's such a small thing, but it still nags at me...
