Hypothetically, say there’s this girl who you fell for the first time she ever spoke to you. Let’s say you thought her sweetness was a fluke until she started flirting a little. Let’s say you thought it was nothing but then the next week she flirted with you again. Let’s say she put her head on your shoulder. Let’s say she was having a boy friend sleep over for the night, and talks about her nervousness at length. And then let’s say she tells you that she feels like she knows you so well even though you’ve ever spent 4 hours together as you walk her home.
