Here then is a very good ambient theme song from a movie (Sunshine) that started out promisingly and took a left turn into bullshit. Get down with some instrumental feels. Or not.
Around the time that this movie came out (2007) I worked with a person that I nicknamed 'Sunshine'. She was an aggressively cheerful and hilariously incompetent person. She worked in my department for about 3 years and she was good for some type of issue or challenge around once a month. The issues varied from wearing pajamas to work to having a nervous breakdown and needing to take a leave of absence. (Though these two things mayyyy have been related in some way.) When she had her final extended meltdown/leave and the company told her to take as long as she liked but to not plan on returning I took over her job duties. The saddest part about her issues was that she hardly did any work at all, and she still could not handle it.
The funniest part about her leaving was that IT gave me her computer so that I could access her files, and her password was "happiness". Sunshine, indeed.
