DON'T TELL MOM THE BABYSITTERS DEAD - One purse in two places?

When Sue Ellen gets home from work and her brother is upset with her for being late. Notice that when she walks in the kitchen she puts her purse down counter when shes talkingwith her brother. At the same time back at the office Carolyn is there looking to see if she stole money from petty cash. When they notice that she didn't Carolyn notices she left her PURSE behind. Thats when she notices that she is still in high school. Why is it at home on the counter and on her office desk at the same time???
