My brother and I are close to six years apart. While we lived in the same school district during our entire school careers and had a few of the same teachers over the years, with the exception of the year I was in 6th grade and he was in kindergarten, we never attended the same school at the same time.
My sons are two years apart. They are breaking new ground for me in this department. They have very different friends and different interests, but that doesn't keep them from looking out for each other. More precisely, it doesn't keep THEIR FRIENDS from keeping a close eye on the other one...and reporting back.
It's not just reporting, though. It's more like a quiz show, heavily prefaced by "It it TRUE that...?"
Isaac found himself in the woodwinds room, surrounded by a group of girls very interested in knowing the facts. "Was it TRUE that his brother was taking SN to the prom?"
When Isaac made the decision not to sign up for band again next year, Alex was grilled by band members in math class. "Was it TRUE that his brother was dropping band?". And even more disturbing: "Does you MOM know?"
I have to love the latest gossip. Over the weekend, Alex got a haircut. His hair had been near shoulder length, thick and extremely curly. He now has a cut that would pass muster at a military inspection. This is big news. Isaac should know...he's had numerous people tell him the latest. "Did you KNOW your brother got a haircut?"
