Like seriously, toxic people are dangerous if not recognised. They act like a snake just as you illustrated, and a green Snake under a green grass is difficult to sight. You can only identify such via it's movement.

The tips you listed are very helpful. Knowing a toxic person is important in order not to fall a victim of unforseen circumstances. Toxic people are toxic to the tonic. They are bitter than bitter leaf, and useless than used tissue papper.

Knowing them is key, so as to avoid them before they corrupt a good course. 👍
