"I just came to see how you were faring".
Isis was not used having visitors around and especially not the Egyptian god of sky and war, Horus. She knew him as one who held on tight to his pride and would not in a god's lifetime stoop to visit another god in the name of just wanting to know how she was fairing.
Besides, she has not seen him since after their fight against Ra and ever since then, he has been out of sight but he never slacked in performing his godly duties. Well how could she blame him for his recent behaviors, while she knew very well how things must be for him now. She knew he was still getting over all of Ra's deceit and the way he used him as an efficient pawn but most of all, his adjustment to Nut's return and letting go of most of his wills and duties for her to resume her work as it was before was really too much on him.
