I have a 20 year old sister, an 18 year old brother, a 14 year old sister, a 12 year old brother, and a 10 year old brother. Yes, we get the Brady Bunch comments a lot.
I have to say, I have taken time with my family for granted. Both my older sibling are doing their college thing now. They commute together, but I RARELY even see them. Because during the time that they are at home, they are either studying or sleeping. Now I'm pretty much the oldest at home, and I miss having my brother and sister here to talk to. I have my three younger siblings, but a younger sibling is a completely different thing from an older one. It's not better or worse, it's just different.
