Oh, I know, I know. You are thinking to yourself "how can you advise about being happy one day and then turn around and advise about dishing out revenge on the next?" Well, let me tell you...IT'S EASY because they frequently go hand-in-hand! Nothing makes you happier than seeing an enemy put in their place! Trust me! For example, let's say a neighbor, hmmmmm, across the street doesn't quite take care of their yard enough for your tastes and indeed might perhaps re-locate a toilet into their front yard during a renovation and they then "accidentally" forget for weeks on end to put said toilet into the construction dumpster. You have two choices: you can sit on your own immaculate porch and wait and see exactly what petunia-pansy-lantana combination they have planned for this avant-garde planter or you can just call codes and complain! Flowers make you happy, but they die. Seeing a city official with a clipboard knocking on an undesirable neighbor's door is a gift that lasts forever.
