The order of nodes in the dialog can affect how the chatbot works.

Correct
For example, the order of the Welcome and Anything else node matters. Some nodes can be independent peers and appear anywhere between Welcome and Anything else. In other cases, however, the order of these middle nodes can matter as well. For example, nodes with generic conditions (e.g., @relationship) placed above nodes with related, but more specific conditions (e.g., @relationship:wife) can overshadow and prevent the execution of the latter.
