Sometimes playing stupid opens your eyes to the truth.
Do not rush to judge someone unless his/her fruits reveal the truth. However, don't forget; mostly, it's not the fault of the tree to produce bitter fruits. Sometimes, the soil determines that; blame the source! Deal with the soil! Don't deal with the tree! Other trees are there that the same soil can influence! Don't deal with your enemy, deal with the satan that sponsors them!
Don't show a friend your gift, or your bag of money if you still want to maintain your relationship, but if nay, go on, and all you'll see is hate and jealousy, and you'll fight with him in the street like a dog and all you'll feel is regret.
The kind of lies that someone tells us gives us an idea of how stupid, knowledgeable, intelligent, or ignorant they are … or they think we are.
