re Matt. Even if people recognises where a quote comes from, when it is posted without a message implies that the person posting has probably borrowed the words to express how they are feeling.

If someone stuck Hamlet's "To be or not to be" soliloquy here, without any explanatory gloss, the fact that a lot of people will recognise where it comes from won't stop them wondering whether the poster is planning to top themselves, especially if they've been sounding a bit angsty recently.

That's how it should be. It's more important to help a friend, including a virtual-friend, rather than to worry about losing face.

It'd only be if people read it in that sense, and then came back seriously encouraging the one who posted to carry on and do the deed, that there'd something to worry about.
