Can mean a lot.

It's not about the word itself has the power.
But it's the mouth speaking out the words that matters.

Words like,
"pretty", "beautiful", "well done!", "good", "that's okay."
Can cheer up a person's whole day.

Words like,
"sluggish", "that's all?", "just look at them", "selfish",
Can "cheer" up a person's whole day too.

It's pretty cliche, everyone knows,
But it's pity how we never really bothered about our words.
What's more when we're around people we so-called "close" with.

"It's just a simple word, who would take it personally?"
