Making Sure There Is No Sweet Behavior Here

(My brother was recently diagnosed as an insulin dependent diabetic. There are nights where previously, our mother was unable to give him his medicine, so I take over Monday nights. Prior to this my brother has made me cry and leave our parents house in tears after insulting me and yelling at me.)

Mom: “[My Name], can you give your brother his shot? My hands are full.”

Me: “I get to stab him?!”

Brother: “…why did you ask the deranged one?”

(I correctly take his blood sugar, and while I’m preparing his insulin, he decides to test my knowledge.)

Brother: “So, how much were you going to give me? My correct dosage.”

Me: “Nah, I’m just gonna kill ya.”
