In my imagination, having a sister would be.... would be, AWESOME! Yeah awesome like you can do mostly everything with her, like shopping, hanging out, bitching your fr/enemy, punishing your psycho ex boyfriend and many, many, many more!
In my imagination it would be like something as fabulosa as this :










PS : I told my parents to adopt a sister for me but they said "just be grateful for what you already have." :(((((((((((((((((
