Lesse...
Peach Girl, definitely. *sniff* When Momo was pounding on Touji's door when he broke up with her and towards the end when Okayasu figured out he loved Momo more than that nurse (whose name escapes me at the moment).
Yu-Gi-Oh, the last episode when Atem left.
Full Moon wo Sagashite, when Mitsuki was in America and she figured out what happened to Eichi.
And of course, during her concert when Takuto... *cries*
Fruits Basket, the last few episodes when Kyo transforms.
In the last few episodes of Air TV when Yukito leaves and Misuzu goes through all that stuff when she loses her memory and whatnot. Oh, and while Misuzu and Yukito were trying to play cards and she bursts into tears. I started crying then too. ^^;
I am a very emotional person. lol, yeah. I'm trying to look for more anime that makes me cry. I have no idea why, they're just very enjoyable.
