# With the Multiuser system. It became clear early on that simply using the UDP
# protocol would not be cool. Because it's just not checking enough things.
# In my point of view. I want to send to the end network all the data directly
# and not care too much about what format it is in and stuff.

# So this file will insure that the data will be transferred what ever it is
# just as is. The hard part will be here.

#                  P for Pain    
    
#    Can't afford to feel the joy
#    Can't find strength to feel the pain
#    I'll shrink and go and feel no more
#    Is it fine to be lame?

#    I don't want death. Since death
#    Has an opposite effect
#    From suffering from being lame
#    Death is opposite of pain

#    An importance of the pain
#    Is that joy is just a drug
#    Such as suffering and pain
#    It's a head confusing bug

#    Joyful, satisfying shit
#    make you feel comfortable
#    But discomfort and the pain
#    It's what is affordable

#    Lameness feel pathetic shit
#    Me described using four words
#    No more joy, only regrets
#    Five more words of discomfort

#    Shrink from big and fall from tall
#    Give up everything you have
#    Go homeless, starve, and suffer. Feel.
#    The pain inducing hollow and venomous discomfort,
#    swallowing all and every thought and only
#    pain. Pain. And nothing more exists.
#    And nothing more is fair.

#    Can't afford to feel the joy
#    But find strength to feel the pain
#    I'll shrink and go and feel no more
#    It is fine to be lame.
