“i was a bur in no one’s saddle.” “he was a walking warning against not brushing.” these both can either be the same or different. —- simile. metaphor. hyperbole. personification. why?

Different, the first one is a Metaphor because it describes him/her as a bur in no ones saddle, and the second is a personification because it describes a warning that is walking.
I may be wrong but I tried.

Where is the sentence? be more specific so we can you
