Emotional contagion

Our emotions can be easily transferred to another person without us even knowing about this. This can also happen through large-scale social networks without in-person interactions or nonverbal cues. Our negative emotions such as anger are transferred more easily than positive ones. 

What you can do: Be aware when your partner or colleague “makes” you angry. You may not actually be angry with them, but instead, mistaking their anger for yours when your brain reflects their feeling states.
