The type of people no one should trust in life.

Class colleagues who won’t allow you to copy their homework.
Drivers coming from the opposite direction who don’t ‘flash’ to warn you that there is a police car waiting 1 km away.
People who don’t admit an edge ball in table tennis, that the ball fell on the line in tennis or that the ball was out of bounds in a friendly basketball match.
Chess players trying to flag you in rook vs rook situation.
Politicians.
Successful ‘enterpreneurs’ offering you all the life advice you need.
People who don’t bother to help you when you ask for their help.
People who use “my friend” in sentences only 5 minutes after you have met them.
People who keep talking and never bother to listen.
Yourself !
