Had a would be robber in college
Was walking girl friend home one evening in college. We had a follower, that I didn't see or hear, but she did. Just as we crossed an alley she turned, gasped, and he ran down the alley. I didn't occur to me until later that that guy was probably a nervous robber. Amazing.
Now days I just do my best to not be in unpeopled places after dark.
Live well, be safe.
