Randy: Natalie, we're dead, look what happened!
Natalie: What's wrong?
Randy: <file_video> 
Natalie: No way, how did Sally and Molly get to the parent's bedroom?!!
Randy: I've no idea, someone must have left the door open
Natalie: It looks really nasty! Why are all the sheets so dirty?
Randy: I think they both went to play in the mud and then somehow ended up here
Natalie: Jesus Christ, mum is going to be really mad! Start cleaning it 
Randy: I know, but it's hopeless, parents might here any minute
Natalie: Just do it, I'll be back as soon as I can!
Sally and Molly possibly played in the mud and got to parent's bedroom, where they made a mess. Randy will start cleaning and Natalie will join him as soon as she can, because parents might be here any minute.
