Yes, this is a really morbid and bizarre topic. I'm not one to sit and pontificate about death either, so hear me out. I'm the youngest of 3 (awwwwww) and also the only one who hasn't popped any spawn out. My brother is in the middle and has a 1-year old; he and his wife are now writing out their will. They asked my sister (who is 11 years older than me and has 2 kids aged 7 and 4) to be the legal guardian if both my brother and sister-in-law die. By no means do I want kids any time soon, but I guess I just assumed since I'm younger I would be first on the list. I'm not insulted by their decision exactly; in fact, I think I'm mildly relieved. What's the etiquette on this typically? I know it's situational in some circumstances, but I'm talking in broad terms here. Also, is it inter-changable like trading household keys with a neighbor? You watch my kids, I watch yours kind of thing?
