PLEASE HELP!

Just wondering the title of this film.

I believe it came out around 2006 some time.

It was about a spoiled girl who worked in a boutique and ended up being fired and ditched by her friends and to make rent she had to work at a burger place.

A middle age man is being divorced by his wife and cannot afford his mortgage so he has to move in with his daughter (who doesn't want him there). He applies for one job, but doesn't get it as he is too old (even though he completes the tests). He also ends up working at the burger place.

The man and girl start a friendship and he helps the girl renovate her apartment.

In the end the girl leaves the burger place and one night sees the man on the bus - she knows he is looking - at first she avoids his gaze, but ends up waving to him.

*I do not remember whether the film was English or French.

Thank you.
