I agree and disagree. The listing people may use in their heads may look like
breadth first, but it's actually more chaotic. If you asked someone to name all
the descendants of a grandparent, they will probably group siblings, and the
groups may be sorted by generation, but within each generation the groups may
be out of order.
Nana
Alice Bob Charlie Dave
Elsa, Frank Gerald, Hector, Isabel Joey,Kevin Lisa
If you ask for someone to list that, it may come out as "Alice, Bob, Dave,
Charlie, Gerald, Hector, Isabel, Lisa, Elsa, Frank, Kevin, Joey"
However, when talking about computer programming, I'd wager that people expect
depth-first, if not for the simple reason that this is how they'd implement it
if they were asked to.
