history: I once woke up in the middle of the night to a weird sound, i grabbed my gun and ran for the door, it was actually the printer. The other night i heard a sound like someone was breaking in my house_comma_ i was pretty scared. 
current: Wow, that sounds quite disturbing. Was someone breaking in?
next: No, it turns out the power had went out for a minute and it was the sound of the printer calibrating.
