Frustration . . .

is when you have to miss your colleague's engagement shower, b/c you have a class to go to
and
you leave work at 4:00 to get to said 5:30 class and are still 45 minutes late
and
by the time you get to class, there's only 25 minutes left of lecture
and
you realize it took you 2 freaking hours to drive a mere 28 miles to San Jose
and
you (slurp) have to (slurp) sit next to (slurp) the guy (slurp) who (slurp) has an annoying (slurp) tic and (slurp) sounds like (slurp) he's slurping (slurp) or smacking (slurp) his lips every three seconds (which I'm sure he cannot help, but is excruciatingly annoying all the same, if he's right behind you doing this, and you are already cranky from the traffic you had to deal with to get here)
and
after all of this, you sit through the remainder of the class and can't make heads or tails of anything that was said during the 25 minutes.
(sigh.)

on the other hand. . .
