last lab...

Haha, just finished the last lab. (declarative)

I didn't know that I was so adversely affected by looking through microscope. (declarative)

Having a slight headache now. (declarative)

Was in the library today looking at some books. Many of the computers were not working very well. I wonder why. Some of the computers keep restarting. 2 cannot be switched on. And there were 2 which were on a screen which I have no idea what it's for.

When will the headache go away? (interrogative)

Sleep. (imperative) I think sleep will help.
