Books that make me cry

I saw Toy Story 3 with my mom last Monday. And let me tell you—I teared up at the end like a four year old girl. I feel like I should send the writers cupcakes or flowers or chocolates, for writing a story so fantastic that I totally forgot it was a movie about toys. That last scene? I felt like I needed to hurry back to my condo to hug AJ Bear (a childhood toy I've still got) and promise him I'd never ever stick him under the bed or in a forgotten toy chest. Ever.

Anyway, that got me thinking...
