My sister's superpower is testing my patience.
My sister's talent lies in finding new ways to drive me crazy.
Behind every successful person, there's an irritating sibling.
The only thing more annoying than a mosquito buzzing around is my sister's voice.
Having a sister is like having a built-in best frenemy.
I have a black belt in ignoring my irritating sister.
Life is too short to argue with an irritating sibling.
Having a sibling means having a permanent partner in annoyance.
