Sasha says I am absolutely exhausted!.
The friend responds Are you not sleeping well at night?.
Sasha responds Well I forgot I had a test coming up and I hadn't studied so I had exactly one night to study all the chapters!.
The friend responds Oh no, been there, done that, I hope you did well on the test.
Sasha responds I feel I did, I mean I studied for eight hours last night.
The friend responds Wow well at least you can say you did the best you could! Get some rest..
