Odd as it is

Sat under the tree was the painter. silently, he gazed his surroundings. 

From what he saw,

a woman talking to a man, looking disappointed, she glanced away.

perhaps, he made an assumption, they are quarreling. 

But from what she saw, 

a man that stood in front her, didn't understand his reasons, 

she looked away and tried to think of what the things he said to her. 

However, from what he saw, 

she was trying hard, trying her best to challenge his words.

he knew she was thinking the best of both sides. 

but, they just didn't see it that way.
