Friday, ~5.30pm, lab
i was still doin my work and the cleaner came in to do her work, she usually starts her work at around 5pm till 9 something (or even later?)
cleaner: it's friday, you should go home early
me: yea i know... i wish i can.
cleaner: well, at least you know you're here helping someone.
me: yea... (smile)

then i thought... helping someone? but i'm doin my own project.
after a few minutes, i'm still thinking wat she means...
oh! i think she means i'm doing medical research, helping the sick ppl.
awww.... touched*

moral of the story is:
see how selfish i am and how she has a big heart
