q is a strange letter, to be honest with you.
i know three persons called "Q"

there's Q from James Bond books and films. 
i do like this old man.. & the films of course.
there's the Q "being" from Star Trek: The Next Generation.
not sure i like this silly character but i sure like the series.
then there's my friend Honza who is nicknamed Květák (Cauliflower), in short, "Q"
if you've read the sections above, you might already know how much i like this Q.

Qi is also a well-known word in scrabble
and it stands for Chi or Ki, of which you can read above.

p.s. Having finished this writing, i found out that my friend Q is currently reading a book called...... "Q"
i enjoy these nice coincidences! :)
