Bleach taught me that you should protect the people who matter to you. And punch your dad in the face when he goofs off.
FMA taught me that you very rarely get a fair trade in anything.
Death Note reaffirmed that "Power corrupts, Absolute Power corrupts absolutly"
K-On! taught me not to give up on my dreams. Which is wierd considering it's... ya know, K-On!
YuGiOh! taught me that papercuts aren't the most dangerous thing that can happen when you wave cards around at each other.
and DBZ is what got me into anime, which makes it kick [All hail lord Xenu]
Although Sailor Moon was the first anime I watched, when I was like 6 and they had it on Fox Kids. Ah those were the days, when I could watch stuff like Sailor Moon and Tenchi Muyo and not feel disgusted with myself that I just watched Sailor Moon and Tenchi Muyo ^^
