When it happens, it will be too fast.
Unexpected tragedy doesn't hit by appointment or when you have a break in your calendar. It hits when you least expect it. Prepare before hand. Have a central location for financial documents and wills (business of life stuff). Share information with your spouse and listen when they are telling you - insurance due in 6 mo - check, spent a bajillion dollars on the new lawn mower - check, it has a warrantee - check!! Above all else, make sure they always know how much you love them. When tragedy hits, there's too much going on to focus. There's the business of life and the emotion of life - each one battles for your time and attention when only one thing matters - the person that you love.
When tragedy happens you'll desperately want time to slow down so you can get your ducks in a row and treasure the time that you have. But you can't slow time down... so do it now before you need to do so. It's a life lesson that someone else has learned recently, that has made a profound impact. We are creating our emergency binder with wills, financial information, insurance information and any end of life considerations. It's not the fun date night activity that we'd like to be doing, but I don't think we'll ever regret it.
