*me mysteriously appears in a puff of smoke*
I don't have any lessons today.... but I was planning to go to
school to do some revision.
However, I felt so groggy and worn-out that I decided to take the
day off studying. I think several consecutive days of studying late
into the night with my veins turbo-charged with caffeine is taking
its toll. 
In any case, I'll be giving tuition later in the afternoon.
Whatever the case, I'll get back to studying tonight.... I have a
test tomorrow.
