Today has been an extremely long day ! We drove for what seemed like days , through what seemed like a hurricane , to Miami . It is my Uncle 's 50th birthday today so we celebrated with him and the rest of our family .

Question:
Why was this event , the uncle 's 50th birthday , momentous enough to be worth such an unpleasant drive ?
Pick from:
+ They had already booked a table at a fancy restaurant , and it was too expensive to cancel on it so they went ahead.
+ They have been informed that their uncle has been diagnosed with terminal lung cancer . This could be his last birthday.
+ The uncle offered them each $ 100 dollars if they would be able to make it to the party , so they were sure to attend.
+ They love their uncle , and they want to support him on this milestone birthday , even if it means bad driving conditions.
