The assignment was hard for me.

I needed to hand out first assignment of comm409 today.
I stayed up all night finishing the assignment.
Whenever I checked the writing, I always found somthing which needed to correct.
Nevertheless, I am not still satisfied about the assignment.
Just the fact that I have no time to improve sentences any more makes me stop checking the assignment.
Anyway, since I already handed it out in the morning, I am lightened in heart now.
I am so tired and sleepy.
I am going to go to bed earily.
