1) An individual whose presence in your life results in most of your interactions with them leaving you drained, spent, and feeling like your own Qi ("life force" energy in Traditional Chinese Medicine) has been sucked right out of you; 2) A two-legged spiritual and/or emotional parasite of epic proportions; 3) That friend who always has some sort of disaster going on in their life that they can't help but impose into YOUR life each time.
My friend's divorce was over five years ago, but every ongoing battle with his ex, over cash and kids, gets described to me in minute detail on a daily basis. The man is a Qi vampire!
ValueVampire - A person who when present, sucks all of the value out of a room.
Owen, Tom and Jordan are together having a great time and are all adding value to each others mood. James arrives on the scene and unbalances the harmony by not adding any value at all and in fact sucking some of the value out of the situation and everyones mood.
When James leave's Owen might say to Tom and Jordan: "I'm Glad James is gone, he is such a value vampire". The mood would then improve as value is replenished.
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
