True/false

Can we discuss the things we use for the tricks we spring on people so trusting.
From up our sleeves, come tears of sadness and tears of joy.
Nothing too complicated for the hearts of liars.
Lies, careless words, for careless people.
Deceitfulness: a trait found only in hate.
And I wonder what defines a lie.
How do you define a lie?
Empty promises leave holes in hearts of many,
some with those intentions, some unintentionally.
The most untamed beast is the beast in our mouths, our tongues.
