Your next door neighbor, Smeshnanda must have been out partying last night because she accidently left her keys in the door. You noticed this when you went to take out the garbage and tapped on her door to try to return her keys to her.
It took her a few minutes to open the door, but when she finally did she came to the door like this and although she was a little tipsy she was so grateful that she invited you in for a few minutes.
