Lou at the end of the movie..Shocking..

When Lou is in Paris and she goes to the perfume shop to buy the perfume Will recommended for her,she was SMILING...I was like,seriously?
I get she felt a bit thrilled seeing the perfume he thought for her, but he had just died, she was at the french restaurant, the one Will visited and she was alone, so she had reasons to be crying instead of looking so relaxed.

That was the place Will visited but he was not there so I would have felt bad and depressive.However she acted like if Will was waiting for her in some place near there..I found the ending totally ridicolous..
