Jane, their mother, suddenly felt an urge to close her eyes, as if she was going to sneeze. When she opened them, Zoe and Jon were gone. She felt strange herself, but shrugged it off and went back into the house.
She froze as she entered. The place looked different. There was a new couch, and LCD TV in the living room...stuff she couldn't afford to give her children on the salary of a single mother.
She turned and entered the kitchen and saw that food was already cooking on the stove...she saw a pot of soup heating up, some vegetables in the steamer...and some meat cooking in the oven. She hadn't done any of that.
She started up the stairs and into her bedroom. She froze as soon as she opened the door. A middle-aged couple were kissing passionately in her bedroom... They pulled away when she gasped...it was Jon and Zoe...cleaned up, respectable, and...
"What's wrong, sweetheart?" Jon asked her.
"You really should have knocked, Jane," Zoe said.
"We probably should have locked the door," Jon said. The two grinned.
Jane felt weak at the knees.
