"Ummmm, Mom? You're blabbering again!"

Reilly was doing a worksheet today where she read a few little paragraphs and then had to mark whether the sentences listed afterwards were fact or opinion. One of the sentences was "Starfish are very beautiful" and Reilly heartily agreed that starfish were beautiful. So, I felt like I should explain to her that just because she (or anyone) agrees with an opinion, it doesn't turn it into a fact. So, I launch into an explanation which was apparently too wordy because when I got done, I said, "Do you understand?" and she said, basically, "Well, when I got done with the worksheet, you started saying all these things that didn't have anything to do with it."
Not my finest teacher moment, I guess!
