dreamy…..
Stupid Rodmans! I wanted
to get into that class.

4. All I need to do is look at her
student ID in her backback, and
then I can call and reset her PIN.
I could reset Alice’s ISIS PIN, drop
her from the class, and then
register myself for the class.

5. Hi, I’m Alice. I forgot my PIN….my ID
number is , and I was born

to You should be able to access it
