In fiction, the most life-changing events seem to happen at family gatherings. No family is immune, but especially not at a reunion, wedding or funeral, though it is also a staple of Christmas Movies. No matter what sort of family gathering particularly one involving a Big, Screwed-Up Family there are shocking revelations, death, divorce or even attempted murder.
If this makes family gatherings sound dangerous, don't worry. There is almost always reconciliation in the end, and everyone comes out of it learning valuable lessons about life, love and the value of family.

His remaining niephlings all prove to be jerks as well, with everyone more concerned about who's going to get the inheritance and the inconvenience of sticking around for the murder investigation than South's death and deriding his daughter for her worry.

- Why Fairy Tail Can't Have Family Unions is essentially about Sting and Rogue trying to talk the Fairy Tail guild out of having one.
