My brother and sister in law are about to have their first kid. Given that my other brother is a priest I'm going to have to be the crazy uncle. My sister in law hates pets, they aren't going to have firearms or weapons in their house, and are in almost all ways average, middle-class, suburban white people. Despite also being a middle-class suburban white guy I'll be the one teaching her how to shoot, make a fire, handle animals, hunt, survive in the wild in summer and winter, probably rebuilt engines, etc. For the other crazy uncles on here, how else can I best undermine their parenting
