Don't open the door

>exclaim out lous "oh gee, I sure have got let myself go lately, I am fat plump and jjuicy and barely fit in my japaneese schoolgirl uniform. How alone and vulnerable I feel and also i accidently slathered barbecue sauce all over myself." then put your ear on the door.
If you hear any telltale signs of tentacles coiling and rasping and/or the wet slurping of a toothy otherwordly maw slaivatin in anticipation of it's next meal of tender human flesh (... we won't ask how you even know what that sounds like), you probaly /shouldn't open the door.
