Duck typing progeny

Two C++ programmers run into each other for the first time in many years at an event.

After exchanging pleasantries, they ask each other about their lives in the time since they last saw one another.

One says, “I don’t know, you do everything to raise your kid the right way, and they betray you.”

The other braces for a comment about how the child doesn’t have the same politics, religion, or ideologies of their parents.

“My child writes in weakly typed languages.”
