A friend who does not show up to drive someone to the airport is not being thoughtful at all and instead, their absence caused the person to miss their flight.
Context: "My friend promised me that he would drive me to the airport but he never showed up and I missed my flight."
Hypothesis: My friend never showed up to drive me to the airport and as a result of his thoughtfulness, I missed my flight
Based on the context, is the hypothesis true, false, or unknown?
