Use your words wisely.
Xiu actually felt like today she understood the meaning of this sentence in a perfect sense. The words you use to describe others can often be used to perfectly describe you. For instance, in the case of Xiu, she loved calling Dylan a dumb person. But today, at this very moment, she wanted to use the same word for herself.
DUMB!
IDIOT!
BLABBERMOUTH!
Most of all, BLIND!
She was repeatedly condemning herself for having a single-track mind. Xiu would never hesitate to accept that she had flaws. Like she was selfish, hypocrite, sometimes a liar as well. But she never thought that her being a single-track minded person was also a flaw. That's something she only realized now.
So, I was reading my notes from yesterday and suddenly, I was like... Meehee, what the hell is 'groundbreaking scene'? I mean where did that even come from?! Apparently, I say a lot of nonsense as well. I guess Xiu is rubbing off on me.
