rage

G.T. wasted too much money on drinking again.

I got mad.

Why don't we save money and go to Germany next year?

danger

There was a mad man at the station last night.
He was howling and walking around the platform.

I wonder which train he took.
I was relieved that it wasn't mine.

burden

Started reading "Harry Potter and the half-blood prince".

The book is too heavy to carry around.
I just have to sit still and read.

discovery

The DVDs have two sides?
I didn't know that.

Now I know why I missed some ER episodes.
