I found this for you: http://www.superteacherworksheets.com/causeeffectfactopinion...

Hope it helps!

You were the one who felt the need to bore us with your opinion. I'm just taking the time to show you how off the mark you were.

It amuses me that my boring opinion means so much to you, that you decided to barge in on a completely different topic weeks later, and rub your own boring opinion in.

I appreciate this unexpected attention, but it is kind of weird of you, and a bit stalkerish.

I think I've already explained myself. Can I be done now?

Of course, just stop replying.
