I have an older sister and a younger brother. This "bullying" you guys refer to isn't bullying to me, it's just an older sister trying to be an authority because she's the oldest, and a little bro being dorky because he feels like it and/or isn't the brightest. Regardless of how they acted towards each other in some situations, they clearly love each other. I never felt either were being too harsh. And if either sibling were getting legit bullied by someone and they were getting teary eyed over it, I'm sure either sibling would stand up and fight for them (and they did repeatedly fight for each other in the game).

If you guys think this is bad, you'd shudder at some of the 'bullying' my friends give each other.
