For those of you that have much older or younger siblings, what is your relationship like with them? My definition of a “large age gap” for this discussion is 10 or more years, your junior or senior. For reasons I can’t find the words to put on paper, I really find relationship dynamics between siblings with large age gaps really fascinating. I’m thinking about writing some interpersonal drama story between a teenager and their adult sibling. Nothing is set in stone yet, but perhaps their parents have recently passed away in an accident or something. Thus forcing the teenager to live with their adult sibling. I picture their previous relationship as loving yet a bit distant. They probably haven’t stayed under the same roof for more then a week, in over a decade. It’s quite plausible that the teenager doesn’t even remember their older sibling ever living with them. Not to mention that they in vastly different stages of life. The teenager is still in high school, while the adult is married and has a number of children of their own. In fact, the adult sibling’s oldest kid is probably only a few years younger then their uncle/aunt. Maybe this causes some issues, as they don’t know to relate to one another. To make matters worse, I’m picturing the older sibling making attempts at parenting their younger sibling, as they do with their own children. Which puts them at odds with the independent minded and semi rebellious teenager. I just want to hear some input, that would me create a convincing dynamic between my two possible characters. Any responses will be appreciated.
