I just came across a conversation I recorded back in 2011 between me and my sister, it went like this.

Me: Do you care for me?
Sis: Yeah
Me: Why?
Sis: Cos you're my brother
Me: Do you respect me?
Sis: No
Me: Why not?
Sis: Cos you're very mean to me
Me: Okay do you love me as a brother
Sis: Yeah
Me: Why?
Sis: Cos you're my brother
Me: That's very [tries to say the word 'sweet']...
Me: Why am I mean?
Sis: Cos you're born like that
