You have to be in a certain mood to appreciate this film, where all the scenes are between our protagonist and only one other person that he's having a conversation with.

If you listen closely, you'll notice all the scenes involve talk of some kind of loss or ending - but they can be divided into chosen actions or ones that were not chosen/ involuntary/ out of one's control.

SPOILERS

Chosen actions mentioned: terminating a pregnancy, contemplating suicide, resigning from a job.
Unwanted losses revealed: death of a loved one, losing one's memory (due to dementia), end of a marriage, losing one's sanity

All melancholy topics - but I rather like how it's done. Actions or situations aren't depicted as right or wrong, they just are what they are. That's life.
