What to say on a St. Patrick's Day card?

Mom and Dad,

While many rhapsodize on the luck of the Irish today, I'm grateful for the Irish traits of grit, persistence, and faith that have helped you heal. 

Thinking about St. Patrick's Day one year ago, the night in the ER, dreadful calls to the sibs, not knowing anything medically, I'm awed by the sheer determination that has moved you forward - from hospital to skilled nursing facility, from skilled nursing back to your home.  

A year later - though your world is still dominated by PT visits and wound clinic treatments, you are walking without a cane, managing your world, and sleeping normally, things we weren't sure would ever happen again.  Those Irish traits have served you well.  

I am so grateful for, and awed by, your recovery.  

Love you.
