For those that do technical support professionally or otherwise, this article will seem strangely familiar:
«Help Vampires are found in every public online community, from those nearest to our hearts to those furthest from our principles.
Instead of consuming of ill-gotten hemoglobin, these vampires suck the very life and energy out of people. By nature they feed on generous individuals who tend towards helping others, and leave their victims exhausted, bitter and dispirited. »
Remember: telling the stupid and lazy that they are stupid and lazy rarely helps the problem (although that trick does work on me when I’m stupid and lazy).
