Question #N1298

When a person is speaking to someone and the speaker is interrupted, it is often considered polite to finish the thought before continuing. In the following sentence, the word "to" is placed incorrectly because it is unnecessary to finish the speaker’s thought before continuing. The comma after "to" is also incorrect because it is a comma splice—using a comma to connect two independent clauses. Which choice corrects these errors? \begin{align*}\text{I was about to tell you a story, but you interrupted me.}\\\text{I was about to tell you a story, but you interrupted me to.}\end{align*}
