Who is this Button for?
For Negators, rollers of eyebrows, 'tsk, tskers' and other esteem busters. 
Those whose company usually lowers your mood.
Masters of passive aggression.
Always remember that people can benefit a lot from listening to your put-downs.
Bring it all down!
Something to consider
- Nasty People How to Stop Bing Hurt by Them Without Becoming One of Them by Jay Carter (Contemporary Books 1979) is a short but classic text on these folks.
