should i be happy?

on another note, this means i can concentrate better :D

and section outing today was hilarious -_-
we were throwing stones by the beach and ruidi drew some physics diagram on the sand to teach us how to throw further

something about how if the force applied upwards and forward is equal then it would be a perfect 45degrees curve. but taking into consideration air resistance, the angle would be 50degrees so .. okwdviforgot

(???)

wlao this kind of people go beach also think of physics ? eh really damn hopeless
