Dear illiterate repeat offender.

Please pick _ONE_ list to send your message to.

Please _TRY_ to make your letter on topic for that list.

The message below has _nothing_ to do with _ANY_ Boost list, nor Boost
at all, and you are soon going to give me a brain bleeding if you don't
stop doing this.

Just because someone gave you help out of pity or morbid curiousity in
the past doesn't mean you can keep being ignorant and ignoring of things
being told to you.

If you cannot grasp the very fundamental fundamentals of communication,
please consider not doing it at all.

STOP. IT.

Merry holidays and whatever,
Everyone (via an angry lad)
