I expected the big thing to be so much bigger, but the way it was blown out of proportion didn't bother me. I think 12-year-olds would make a bigger deal of Taylor's actions than we would. Did Henry and Lucy hang onto a ridiculous grudge for too long? Absolutely. But I think it had less to do with what Taylor did and more to do with the feeling of losing your best friend without a word from her, of losing your friend and first love without an explanation. At 12, I think that could hurt a lot.
Interesting to get your take since we had differing opinions on it. :)
