This dicho is somewhat akin to an earlier dicho which discussed being known by the company you keep.  It's a dicho that is used to provide advice to others about who they might be associating with or some type of mischief.  While they may not be the person that "pulls the trigger" or did the act itself, they are just as guilty by being around those who committed the actual act!  It's a reminder to all, especially the youth of today, that hanging around with those that tag graffiti, take part in hazing or bullying, or some other type of mischief will be judged just as guilty for being there!  It's advice that parents should share daily with their children, as well as teachers with their students, since the temptation and pressure by some of the their peers might overcome their initial resistance. 

As mentioned before, through his courses taught at California State University, Fresno, and his experience in the world of entrepreneurship, Mr. Flores was invited to Poland and Belarus where he taught a class on entrepreneurship to young university students that were interested in starting their own business, this after a lifetime of living under the thumb of dictators who discouraged free-thinking and any thought of entrepreneurship.  In Belarus, what made the experience noteworthy was that the housing was very primitive along with the facilities at the university itself, such as their bathrooms and kitchens, even though the university was large and thousands of students were enrolled.  One thing of note was the cafeteria menu, where the meals being served consisted of potato soup, potato salad, potato pancakes and very little else.  Mr. Flores and two other professors also visited a pizzeria that advertised all different types of pizzas.  The three of them decided to each get a different small pizza and then share among themselves the different types of pizzas.  One ordered a salami pizza, another one ordered an Italian sausage pizza, and the third ordered a combination pizza.  All three received a "chicken" pizza!!!  Yes, it was quite an experience dining out in Minsk, Belarus!!!
