Possibility that my Girlfriend is lurking on this site. Should I watch what I say?

[Mercury]

I dont have any reason to believe this, but call it gut feeling. I think my Girlfriend/ ex girlfriend/ what ever the hell she is, found the site, and knows my User name. I mean I have nothing really to hide at all, but I'm not sure if I should exercise caution while posting.

I was going to post something that happened tonight while I was at dinner with her friend and there family, but I dont want to cause there friendship any problems.

As I said, no reason to think so, but my Gut feelings are usually pretty acurate. What would you all do?
