Joe Dowling directed numerous productions of Philadelphia, Here I Come! for the theatre. He once said that that the play dealt with our inability to communicate intimately, especially within the context of Irish society. The father and son relationship of S. B. and Gar highlight the extent of this communication failure. The blue boat scene is important to Gar. It reminds Gar that there was a time where his father and he communicated with each other in such a way that was carefree and affectionate. When S.B. cannot remember the trip in the blue boat, Gar is hurt, and it reminds him of how distant his father has grown from him in the relationship. As the play ends, we find out that S. B. remembers Gar’s first trips to school in the same way Gar thinks of the blue boat. S. B. allows his son to leave at the end of the play, even though it will be difficult for him. The audience can infer that this is because S. B. loves his son, despite his inability to communicate it effectively.
