Like some others have posted, the "not your day" thing is all backward. You had something/somebody looking out for you today. Glad you're ok.
When stuff like that happens, it's a good reminder to take stock in what you DO have. Whether it's hugging your kids, your mate, or just looking around and realizing that you're healthy and have a warm/dry place to sleep at night, it's a little reminder of what CAN happen.
Anyways, sheet happens, and today in fact it didn't. Be thankful.
