LOL. I remember
Since you are also a nerd, you will find this, which I just thought it was related, interesting:
In the area of the Theory of Knowledge, there is this thing called "Gettier Problem" , in which someone just incidentally happens to know something without it being a "Justified True Belief", which is the canonical account of knowledge. The "Gettier Cases" of knowledge are independent and regardless of the usual reasons by which we get to know things.
Likewise, beings friends and falling in love go through completely different paths, so one just incidentally can concur with the other (though usually, infatuation goes directly against the development of friendship). So is not really like limerence, or infatuation, "transitions" into friendship. That on itself cannot happen. It can only happen that friendship develops besides and despite of that.
