How we cite our quotes:
I was in love with her, even though I didn't know her. Kind of like love before first sight. (9.02.16)
Ethan has been dreaming of a girl, and these sure aren't typical teenage boy dreams. This is some pretty powerful stuff.
I watched Boo Radley lope slowly after [Lena's car]. At the rate he was going, it would be sunset before that dog got home. Sometimes I wonder why he bothered. Stupid dog. (9.15.104-05)
Where is the love here? Ethan is criticizing poor Boo for following Lena when—wait a second—that is exactly what Ethan is doing. Ethan would follow Lena anywhere—he just hasn't realized it yet.
You know that expression, "It hit me like a ton of bricks"? It's true. The minute she turned the car around and ended up on my doorstep in her purple pajamas, that's how I felt about Lena. (9.24.1)
Ethan pretty much says it all here. His feelings for Lena are sudden, heavy, and just a wee bit suffocating.
