Word of the day is: de minimis

I thought I might talk about this word but I don't understand it. I think perhaps I could say, "I was quite tired at the time I got angry but that is de minimis, I was angry because he shot me in the knee cap" or something like that.

I think I'm bored. The problem with days off is I have nothing to do. I don't allow myself to do work of any kind and so I search for things to do. I should go see a movie. In half an hour I'll go to church for a creative worship night. Now there's something to talk about...
