did you listen or just hear me?

There's a difference between the two.

When someone says they heard something they don't always know exactly what it was..

"I heard a sound"

"What was it?"

"I don't know"

It's a sound you heard it but you didnt understand wtf it was.

When you listen, things become clearer, you start to understand.

Understanding is important, because empathy is important. When people speak there are emotions and thoughts that are trying to communicate with you. Words without meaning are nothing, but the words will always have meaning. It's up to you whether you hear, or you listen.
