I don't really want to admit but I'll share some of those times(animes that I've seen) that made me shed tears...
Detroit Metal City (i just couldn't stop laughing, my tear glands wasn't able to hold back either)
Fruits Basket
there's a lot of times but it was episode 8 when Hatori's past was revealed(even though I've already seen it thrice)- that made me shed fountains of tears... I just wasn't able to stop it from flowing...
Chobits
episode 22 where Ueda's persocom(already malfunctional) pushed him aside to save him from being hit by a truck... :cry:
and there's actually a lot more...
gintama, lucky star, hajime no ippo, major, kaiji, etc, etc.
I'm not in the habit of crying mind you...I just feel for the characters.
