Id say the past as nearly everyone has something to hide, But also death as a dear friend of mine recently took his own life and it was so hard to speak with his mum after what had happened as she was so sad, the tears in her eye's had me bawling and the funarel was awful, my bf had to stand up and make a speech on what he loved about his mate and looking at his mum crying he broke down so death for sure as well.
