What's the "Sorry" For?

As I was cooking dinner, Matilda was sitting at the counter doodling on a paper, claiming she was writing a note to Tim. Here's what it said:

Dear Dad,

I hope you have a great time at work. Sorry. I want you to come home.

Tim has been back to work now a week now and we are all adjusting. The kids both miss him lots during the work day. Matilda asks for him often and Porter gives him so many hugs when he arrives home. I am bracing for my first full week back home on duty with 2. I think I might need a pack of Red Bull or something until I can build my endurance back up!
