Call me paranoid

So I'm chillin in the basement doing my thing and I hear talking. Usually no one is in the office this early and definitely not multiple people (excluding myself of course). Not really paying attention to the 1st floor chatter but my ears chime in on "I don't want to use speakerphone, let's go in the back so Monique and people can't hear" not really sure who and people are, but why couldn't it be one of them and I'm a part of and people.

No idea what's going on, but I'm a little on edge.
