Say you have 2 glasses of lemonade(that were put there by two different people): one contains poisoned lemonade and the other one is just common lemonade. They are both sweet and taste the same, the only difference is that one will kill you the other one won’t.
How do you know which is which?

Find out who poured the lemonade in each glass!

The truth is not in their words but in their actions, not in what they say but in what they do and did.
