If Lily and James had survived I am positive that every time Harry got in trouble there would be a huge betting pool on whether the next howler would be from either James and Sirius congratulating him or Lily screaming at him and ordering Severus to give him detention for a month.

And as the Potter family owl would arrive, everyone would be silently anticipating the results and at the end you'd see Dumbledore discretely handing Minerva 10 galleons.
