Addiction

An addict is bad enough, both to themselves and others. Addicts
encourage the use of that which they rely on. This isn't good, but it
can still be glossed over.
However, when said addict has charisma then the trouble begins. A
friend of mine loves the game world of Warcraft. Now this isn't too
bad an addiction but it has it's own problems, which I won't go into
detail on. The trouble is that she's pretty, charming and as a result,
somewhat charismatic. She has, therefore, convinced another friend of
mine to join her in the potential money and social drain of the
mmorpg, namely WoW.
