It's funny. When you have nearly 13 years between your kids, you wonder what, if any, relationship they'll have growing up. But one thing that has always been obvious between my oldest and youngest is the sheer pleasure they derive from each other. Marcel has a greater need to return to the nest more often than most teenagers who've left home, because he feels he too has some sort of parental responsibility for his youngest siblings. And Amaia is absolutely thrilled every time he walks through the door. She loves her Monday school news to be something about her ever-so-exotic brother who lives in Edinburgh. She drops him nonchalantly into conversation when classmates are often still sharing a room with their less-interesting siblings.
