People make mistakes in what they do but the mistakes that hurt the most are the ones that are said. 
Say what you need to say, by all means. Just, think a minute before you do to make sure you actually mean what you say. 
An ambush of lies. Half-truths? 
The worst thing is, it actually sounds like the truth. 
And the truth, though actually a lie, falls tenderly on an unsuspecting ear. 
When the lie is revealed, it is too late.


Oh, what a tangled web we weave when first we begin to deceive. 


One can tell the 'truth' was a lie only from it's sting.
You can't take back what you've said, you can't change what the other person felt when you said it. The damage has already been done. 
Next time, make up your mind before you open your mouth.
