This needed to be said.

Politeness: Behaviour that is respectful and considerate of other people.

I feel like some people here really need to learn about this. Politeness should carry into your life, and that includes your internet life.

If you roleplay with someone, and don't feel like doing so anymore, let them know, instead of vanishing up on them.

Imagine you're on a date, the person is not into you, so they say they're going to the bathroom, and never come back. You wouldn't like that, right?

If you roleplay with someone, they'll put their time and effort into it, and they might also become emotionally attached. The least you can do is let them know that you're not interested anymore, instead of leaving them in the dark. It's called being polite. And honestly, you'll feel so much better after ending something you're unhappy with.
