Sounds like Rover was a little distracted on the way to the local book repository. Wait...the dog chased Tim...oh. What we have here is a case of misplaced modifiers. The meaning of the sentence would be clearer if the modifier was closer to what it is modifying: On his way to the library, Tim was chased by the dog. Or reword the whole thing: Tim was on his way to the library when the dog chased him.
Clarify the following:
- While driving to the gym, the dog slobbered on Isabelle's jacket.
- John said he would stay home first, then he changed his mind and went to the movie.
- The captain steered the boat into the pier blinded by the fog.
