why coffee don't work

If there is such a thing as genetic immunity, probably mine is Caffeine. My grandparents chugged coffee like beer on free flow nights, my aunts and uncles have a mutual bond with coffee. Though my parents don't do coffee, i believe the habit of coffee chugging runs through my veins and thus, my body learns to accepts caffeine more than the average people do - even though i am not used to drinking coffee.

you know what, i took that back.
my heart is racing, but i still want to yawn and all that.
i want to move around and lose this chest jitter,
but i can't cause im in class.
i think i need some water to normalize this rush.
