have u ever felt like this: after a whole day of studying, u stand up and pack ur bag, as u're packing, u try to recall everything that u've studied (or at least part of it) and realised by the time u've fnished packing up... u still cant recall anything...... point is, u've juz FINISHED studying, why do u feel like u've not studied at all? my brain feel so empty im sure if i knock it hard it'll produce a hollow thud.

is my memory that bad? have i wasted the whole damn day?
