It has been four months since they were somewhat estranged from their friends and the day of their return was approaching, they decided to buy something for their entire family and for their families, ignoring the calls that their friends had made to them long ago.
As soon as they were at the New York airport "John F. Kennedy Airport", they saw all their respective there but not her friends, which deeply hurt her friends, the fact that they weren't at the airport.
They greeted their families, hugged them, and thanked them again for allowing them to make that trip.
When each of them was at their respective homes, what they did was call their friends to tell them that they had already arrived but their calls were not answered. They saw the time and realized that it was late, so they decided not to insist.
In the morning, when they were able to wake up, what they did was call their friends' houses again, but to no avail.
