Why humans always shout at people while they're angrying?
This is because their hearts were far apart while both of them are angrying.
Therefore, they tend to raise their voice to hide the far distance between it.
Anyhow people who shout will get more & more angry & so the distance is further & further..
That's why people often shout louder & louder..
On the other hand while couples were in love they talk softly instead of shouting because their hearts were together as one..
When the love goes deeper & deeper.. There's no need for a single word for them to know what was in each other mind..
Lastly, just a reminder that when fighting time, don't let the hearts between you & the other get further..Cool down firstt..
I'm trying my very best now =)
