They say it's sad.
When you go to the airport.
Usually is for a farewell, a temporarily good bye.
People come and go.
Visitors go back home.
Others go for holidays, long ones.
People hug. People cry. Then they smile.
One remembers all the good times.
They say things like:
"I'm going to miss you"
"See ya soon"
"Thank you"

This summer... this summer was my airport.
Now is time for me to board my flight.
Not sure if I'll be back.
so.. just in case i don't...
"Thank you for this amazing journey"
