dangerous-smoll answered your question:
Can I set fire to my siblings?// yes, as someone with siblings. I wholeheartedly agree
Good cause my older brother is a dick who keeps throwing spanners in the gears of my life.
// Then instead of fire, may I suggest you put chilli powder into his underwear
I like the idea of using both on him, the chilli powder in his underwear would be easy if he lived with me, but the fire is easy cause he is coming over tomorrow.
