Milli began quietly slinking around to the back of the house.  She wished she had had time to gather her tools but she had had to leave in a hurry.  Once at the back she checked the back door to see if it was locked.  If it was locked she would attempt to unlock it (35 to open locks, 24 hide, 34 move silently, if any of it is needed), if it wasn't she would open the door as quiet as she could.
