"Young man, be aware of these four enemies disguised as friends: the taker, the talker, the flatterer, and the reckless companion.
"The taker can be identified by four things: by only taking, asking for a lot while giving little, performing duty out of fear, and offering service in order to gain something.
"The talker can be identified by four things: by reminding of past generosity, promising future generosity, mouthing empty words of kindness, and protesting personal misfortune when called on to help.
"The flatterer can be identified by four things: by supporting both bad and good behavior indiscriminately, praising you to your face, and putting you down behind your back.
"The reckless companion can be identified by four things: by accompanying you in drinking, roaming around at night, partying, and gambling."
That is what the Buddha said.
Summing up in verse, the sublime teacher said:
The friend who is all take,
The friend of empty words,
The friend full of flattery,
And the reckless friend;
These four are not friends,
but enemies;
The wise understand this
And keep them at a distance
As they would a dangerous path.
