I will not begin to even try to comprehend how hard this time must be for him. I don't think any of us can know his heart and mind right now.
I can only say that in the time I knew Joe and Heather, I can to believe that Joe is truly the best husband and MAN I have ever known. This man fulfilled his duties in every role of his life beyond expectations - as an employee, as a friend, as a husband, as a father. I do not know how he does it. Joe and Heather belonged together because they are both so incredible. [people use that word, incredible all the time, but here I do not use it lightly and in every way, it is 100% applicable here]
Theres a lot I could say here, but for this, I feel brevity is best. I will leave you with thoughts of Joe. A man experiencing perhaps the most difficult time anyone can face, yet I KNOW that he has given his children a beautiful Christmas and that somewhere, Heather knows her family is loved and doing OK.
