Thinking of things

I am a thinker, i am always thinking things even though when i don't want to.
This month,i am in community service. But they sent us to a small clinic.
This is a way of making money between them, i can agree with that.
But what i hate is they are making us to listen to old timers.
70 yr old men, who have had a good time. But now are impossibly out of date. They have large ego. They have a lot to say.
And they want to talk, but we don't want to listen.
what a waste of time.
