I have found the "What 1 thing" thread very helpful - because you always want to support friends when they are going through rough times, but it is often hard to find something to say.
I know I have said stupid things at times and I was wondering if it would be equally useful (and cathartic) to remember the awful things that people said - so that we know to avoid them!
I'll kick it off with "oh well, apparently everyone loses their second. It's your body's way of telling you it isn't ready yet."
