Do not let anger consume you when someone lies to you,
We all lie.
In the first place we lie to ourselves.
Actions speak louder they say, and that's true.
Before you realise a certain lie, you avoided the truth through actions,
We sometimes turn a blind eye, and when things become too big to be hidden we decide to see.
When someone lies to you, you lied to yourself first. For not being true to yourself and turning a blind eye.

People lie to us because we lie to ourselves in the first place. We want to see things as we wish they were not as they actually are.
