So if I understand correctly, I am to leave a pre-recorded message so people will be able to leave myself messages? Wouldn't that entail me predicting what they require? Unless I merely leave a generic response?

Ah, um.

Hello, mysterious person who has reached me. I am not able to receive your message right now, so please leave it here where I will read it upon my return. If I learn how to read pre-recorded messages. Are they like when people leave videos on the network? Is it public, or locked?

Locked, possibly, it is our own perso-

BEEEEEEEEEEEEP!
