A __________ line.

It's been 5 days since I've blogged. Wanna blog but somehow nothing's coming into my brain.
Was brushing my teeth when what Fangting said ytd popped up into my mind.
She's studying the Dentistry course in NYP. Went out with her ytd...then she saw my teeth she said I must have eaten a lot of fluoride stuff that causes my teeth to have white spots on it.
So I asker her what can I do to make it stronger again? She said Fluoride. Then she carried on saying Fluoride can harm your teeth, but at the same time, help your teeth too. Just like how love can harm you and help you too.
Then thinking about it, yea, that's true. But the thing is, it's just a fine/thin line between harm and help. It's about development. A not-so-developed set of teeth can be damaged due to Fluoride. But a set of developed teeth can be further strengthened by Fluoride. Just like an immature teenager pursuing love = can most prolly end up being harmed? Compared to a matured adult? Agree? (the love i'm referring to uses the model of courtship from my prev post.)
There are 2 sides to everything. & it's just a thin ----------- that's separating them. Like GOOD| BAD. FUNNY|LAME. HELP| HARM. LOVE|HATE.
And there's no standing in between them. How can you love and hate someone? It's somehow not possible. Or rather, impossible.
