Nothing has to be done into active voice

Explanation:

Nothing has to be done actively, ( wait what ) I have just thought about this and I think that nothing has to be done in an active voice, like if you're mute. But, if you did nothing in an active voice, would you be able to understand anything? You wouldn't be able to talk or sign language. I don't know if this is a real concept to look into but I think it's pretty interesting. If you don't have an active voice or if you aren't active, how will you live? If you aren't active, or actively talking, then you can't really talk. I mean, you can talk here, but will you ever be able to understand the real world if you're not talking with your active voice your whole life? I hope you understand this and umm, cya! ^^

Hope this helps! <3
