I quickly tried to cover up and scrambled around. She asked me some question but I felt myself turning red and just said "I dunno."I could tell she knew I was lieing. She quickly replied with "You don't know? Oh c'mon you know everything about this stuff!". She stood behind me with her arms crossed. I still sat there, looking at my computer.
