What's the hardest things you've ever had to tell someone?

1) "I love you" - that was easy to tell Laura
2) "Marry me" - that was also surprisingly easy
3) "There's a reason I've not come home from 9 weeks..."
4) "Mum, Dad... there's something else... Tom... ?" - that was the hardest thing yet. An action rather than words this time
5) "Mum, Dad - Laura has something to tell you..." [I go for a quick run to Spain]
6) "Gran... you're not in Germany, you're in Finland"
7) "I do" - I know it will be easy for me to say... in English anyway

So what about you?
