new pet peeve

So we're not allowed to use the phone in the computer lab. I accept that. I agree that it is horribly annoying to the other users in the lab. So here's the thing, why is it ok for somebody to use the voice recognition thing in the lab? Doesn't it do the same thing? I've been horribly annoyed by this guy that has been here doing that every single time I'm in here in the lab. I need to concentrate to do my god damn homework dammit.... jesus christ....
