You know what's pretty scary?

When you're exploring on some random rooftop and a couple of your friends go scout ahead while you're wrapping up your grappling hook, and then you hear from not too far away the "WEEEOOEEEOOEEEOOEEOOEEEOOOEEOO" sound that means GTFO time and your friend's girlfriend who decided she didn't want to climb some weird random ladder is like "what's that noise?" and I'm like "ITS THE ALARM. I DON'T KNOW ABOUT YOU BUT IMMA PEACE" and then I got out of there.
