Start asking around you male friends what their middle names are. Lots (LOTS) of them will have James as a middle name. In the 1980s it was the most popular middle name, along with John, and both were used twice as much as the next name. It is SOOOO common as a mn that I don't think anyone would really notice.

If the two little boys are seeing a lot of each other, it might be like a special bond between them, KWIM?
