I Never Got the Chance to Say Goodbye

I feel guilty that I couldn't say goodbye to my father properly before he left for his heavenly abode. Although I talked to him in his last moment, he was in a state of coma... couldn't hear anything...couldn't open his eyes...
As I stay away from home I reached late. I could have made it if I would had taken a flight but I chose train as I was nervous flying alone. And now all that is left is 'IF', 'IF' and 'IF'.......
