An anonymous writer at Jezebel examines her guilt:
When you first meet someone … you don't actually see them. You see a flimsy construction of their personality, created by your interpretation of the signals available. The way they make eye contact. How they interact with the bartender/waiter/homeless man asking you for change. The facts they choose to divulge about themselves. Because you have no other point of reference, every little detail resonates with added significance. Your mind, faced with a scarcity of information, is forced to create a projection of them. … The mirage is sexy. But herein lies the danger. The potential for a schism to exist between the mirage and reality is huge. The probability of being disappointed is gigantic. That disappointment is compounded when intimacy is involved. You sleep with a stranger. You feel like you know them. But you likely don't at all.
