Tweaking Tall Tale

Tall Tale is a story that is very much in a state of flux at the moment - aspects are being added and chopped off all over the place.

The story, as of the date of this post, is as follows:

A little boy buys a book about birdwatching. Eagerly clutching his camera, he dashes off to search for birds to photograph. He sees a bird on the shoulder of a very tall man, but it flies off before he has a chance to photograph it. The boy walks off screen, determined to find it again.
The tall man is momentarily pleased by the sight of a bird perched on his shoulder, but once he realises that the bird's gone to the toilet down the back of his coat, his mood darkens. We follow him for a little while, as a series of small mishaps, mostly regarding his tallness, make him more and more frustrated (this need only go on for as long as it takes for people to realise he's unlucky).
Defeated by the terrible day he's been having, the tall man sits on a park bench. He doesn't notice the boy run past, chasing the bird until he sees it perched on the branch of a tall tree. The boy determinedly climbs the tree and gets onto the branch, but loses his footing.
The tall man hears a cry for help, and looks up to see the boy hanging for dear life. He jumps up and dashes to his rescue, catching the boy just as he falls. The boy is very grateful and hugs the man, who feels better about his tallness.
The boy displays sadness about not managing to get a photo. The man picks the boy up, and uses his height to provide the boy with a safe means of photographing the bird. Once the photo's been taken, they admire the photo on the camera - including the bird, who flaps down onto the tall man's shoulder to look at it. Everybody's happy, until the man realises that the bird's pooped on him again.
