Cover art for My Sister lyrics by Juliana Hatfield

This song has a contradictory message of feelings towards the sister of the singer. Of course, it can be referred to the singer hating her sister because she left on her own will, but with those feelings just being a cloak for her true love.

On the other hand -and I quite agree with this interpretation- it's a songs which narrates the change of a point of view in our feelings towards our siblings as we grow up. Typically we fight with our older brothers or sisters when we are kids, but as we grow up, we can begin sharing interesting experiences with them, such as being taken by them to a concert. That's something which could be ordinary for a 20-something, but extra-cool for an adolescent.

A relationship like that and related experiences can really build a strong bond, a bond which would deepen the grief at the death of thatt older sibling.
