You got that right Smillew! I've been with a couple of people as they were going out recently. Not at the exact moment, unfortunately, but on the way. They weren't laughing. Kinda hard to laugh when you are experiencing pain and suffering.
I remembered to say the sort of thing you will wish you said if you don't say it. I told my brother I loved him, and I told my ex, the mother of 2 of my children, that she was the she was the most beautiful woman I ever knew. I expressed it in the present tense, because it's still true.
More information than you require:
About my brother's death
