Or you could send a card through the mail, with a personal message. This would help relieve Jo's burden right now.
Thanks Wendy. I've been checking all day for an update.
Here's that link again - go here to send Tommy and Jo an e-greeting at Memorial Hermann hospital. A volunteer will deliver the message. (this seems like a good way to wish them well without intruding...)
Enter patient's name: Thomas Thompson
Select "Memorial Hermann Hospital" in the drop-down Location box. There's a bunch that say Memorial Hermann Somewhere-in-Houston Hospital - choose the one that just says "Memorial Hermann Hospital"
