Oh my God.. I cried during Jessie's sad story in Toy Story 2, truly heartbreaking, beautiful!
And that bit when Woody is seriously thinking about going to Japan and he overhears You've Got a Friend in Me play on the TV show which reminds him of Andy
The incinerator scene in TS3 where all the toys are holding hands really got to me, and the beginning featuring all those flashbacks with You've Got a Friend in Me playing is now tinged with real sadness
The part when Andy played with his toys one final time with Bonnie was beautiful
I welled up during the song I See the Light in Tangled - very moving
