Today I took a break from work because I had something to do.
When I went to a rental CD store and rented a CD and went home, my PC couldn't record the CD.
My PC has a lot of broken places and I have to buy a new one.
By the way, I'm terribly sleepy now.
I slept for about an hour, but I'm still sleepy.
After posting this, I will go to bed again.
