two canadians board a bus. one canadian is the farther of the other canadian's son. how is this possible

The two Canadians are husband and wife.

We do have some very nice Canadian females up here, and most of them have nice fathers, not farthers.

This situation is possible if one of the Canadians boarding the bus is the mother of the other Canadian's son. In other words, if the two Canadians are a mother and son duo, then it is possible for one Canadian to be the father of the other Canadian's son.

To visualize this, let's break it down step by step:

1. Assume there are two Canadians, let's call them Person A and Person B.
2. Person B is the father of Person A's son.
3. Person A (the mother) and Person B (the father) are both present and boarding the bus together.
4. Therefore, both Canadians are on the bus. One is the father, and the other is the father's son.

In this scenario, it is crucial to understand the relationship between the individuals involved and consider the possibility of a mother-son relationship between the two Canadians, which would make the question logically consistent.
