Mom: You are so ungrateful ! You always sit around and do nothing

Mom: You are so ungrateful ! You always sit around and do nothing !
 Me: I'm telling my brain to tell my heart to pump. I'm breathing in and out and fighting disease as we speak. And even if I was dead, I would be slowly decomposing and being food for worms so technically I would be helping flowers grow.
Doing nothing, huh ?
