HARD TO SAY GOODBYE

I'd been back home in Ireland just to visit some old friends
But the days had gone by quickly, it was time to leave again,
And I'd had so many wild nights in the week or two that passed,
I was almost glad that this would be the last.
But I didn't sleep at all that night. I stayed up 'til the dawn
Singing songs and playing tunes 'til everyone was gone.
By then it was too late for me to go back home to bed,
So I opened up another beer instead.

CHORUS: Back across the ocean to my home away from home,
Glad to be returning, but sad to have to go.
I'd like to find a way to be two places at one time.
It's easy going back again but it's hard to say goodbye.

And I had one bag too many just as I was set to leave.
I was loaded down with bacon and with sausages and tea,
And I couldn't find my ticket as I'm walking out the door
'Til I emptied all my bags out on the floor.
On board the plane, I sip a drink while waiting for the meal,
Just trying to keep my head from knowing how my stomach feels.
There's a baby right behind me making sure that I won't sleep
And the flight's too full to find another seat.

And I'm trying to fill out customs forms, but I can't find a pen.
I'm swearing softly to myself I'll never fly again.
There's a woman right in front of me keeps playing with the seat,
And someone nearby never washed their feet;
But I fall asleep at last just as the plane is touching down,
And I age ten years just waiting for the bags to come around,
But finally I make it home and I'm barely settled when
I'm already making plans to go again.
