It might be kind of cool to have an alarm clock that didn't tell you the time in the middle of the night. That way, whenever you wake up 3 minutes before your alarm goes off, you can go back to sleep and not know if you've slept for minutes or hours, amirite?
Nah, once I wake up in the night I have to know the time. Like, I wouldn't be able to go back to sleep if I didn't know.
Turn your clock so that the numbers are facing away from you?
That could work! (: But for me, I just look out of habit. I would need one that stopped me from doing that!
