In Sigalovada Sutra, Buddha gave teachings on how to distinguish good friends from bad friends.
There are four types that are not really your friends, but will make your life miserable in the long run:
1. The leech whose appropriates your possessions
2. The bull-shitter whose manipulates you
3. The boot-licker whose flatters you
4. The party-animal who encourages you to do the same
A good friend, on the other hand, is one who...
1. is always ready to help you
2. is steady and loyal
3. provides good advice
4. is sympathetic
I work in commercial world for so many years and I can confidently say that there is no true friend in working place. Those who I thought are friends will be my 'friends' as long as I can benefit them. Once there is a problem, they'll turned their backs, worse, a few would 'stabbed' my back even I have helped them so many times...
However, I am happy to note that I found true friends in Dharma center, though not all but there are quite a number of them. They are different because they really think for your benefits. I am glad that they are people around me that I can really rely on in bad times
Bad Friends come for Good Times;
Good Friends stayed in Bad Times.
