For the record Moo, there is a specific reason why the ending of Toy Story 3 made me cry.
Spoiler:
Like Andy, I am a sad, lonely weirdo who has for years held on to all of my childhood toys, and still keep them all in my room because I have such an emotional attachment to them that I find it impossible to let them go. So seeing Andy give his toys away at the end of the movie just got meh all emotional and shit.
