working 9 to 5

it's a cliche, 'working from 9 to 5'.
and i literally attended a technical meeting from 9am to 5pm today.
well, actually it was 9am to 5.55pm. minus the 45 minutes lunch and a few 5 minutes smoking breaks in between.
huuuaaaaaarrghhh... so tiring.
fortunately not a boring one.
at the end of the session, i get to have a one-to-one session with the boiler vendor, to understand more of the steam boiler design.
interesting.
one more knowledge today.
alhamdulillah.
