I wouldn’t call it a case of “backburner become frontburner.” It’s more of viewing the same thing in an ever so slightly different light that has the effect of completely changing your perspective on something. Case in point: Sarah McNerney.
We had physics and chem II together last semester and talked quite a bit. I was interested in her, but later found out she was dating. About 5 months ago (as I learned last night), she broke up with her boyfriend. She’s messaged me a couple of times on Facebook and I’ve really thought nothing of it. But if you put the piece together, it actually amounts to some level of interesting on her part (plus my interest). Long story short, I think we’re dating now. I’m going to verify today just to be on the safe side.0
