Tone / Reply / Hurtful / Sort of

Sometimes we were so comfortable with people around us that we didn't know actually we have had offended with the words / answer / sentence / expression we said / used.
Sometimes we wonder why things suddenly turned soured. We thought we wasn't in the wrong. But if you yourself couldn't find the wrong, there's nothing others can do.
What they said, you wouldn't really bother. Their advice, to you, maybe doesn't really "wakes" you up. So well... Heh. :/

But, we might want to take note of our tone or reply to people. Sometimes it's really hurtful. Maybe we should really reflect what's went wrong then.

“呵，你有。”
