yeah friday again

Have no class on friday but spending the whole afternoon at library, catching up some lecture notes. Friday mood is always relaxing, can't really concentrate but I am trying hard. Almost every 20 minutes i was like looking around... and I noticed this phd student that i know, sitting there so long, reading and no movement, static... I wonder how people can concentrate that well... probably as you get older, you get better at it... like a baby or a kid will be active every moment, teenager gets better, but still hyper most of the time, and right now at least I can focus on something for 20 minutes, probably a phd student can concentrate for an hour or so, and my dad, he can spend a whole morning reading newspaper.
Squash again in the evening. Met a new friend. Pretty good player... and we head for tennis after squash. It was so different from squash and of course I suck. and yeap, first karaoke of the semester... so much fun.
