Variance: Weird thing that just happened at work

[Coffee]

I just answered the phone, and a guy wanted to talk to my boss. I asked him for his name, and he said his first name, which happens to be my first name. My name is a bit unusual(Bart), so I was a bit surprised, especially because the guy just said his first name, like I would do if I was calling the office, and his voice sounded reasonably similar to mine. I'm now wondering if that's another guy named Bart, or if my future self just called my boss to warn him about something, and if so, why wouldn't my future self just tell me about it?
