What happens if you have a heart attack when daddy's not here?

This is the question my 10 year old daughter asked tonight as I was saying goodnight to her.  It's a good question, a scary question, a question she shouldn't have to ask but does.  When Robbie is teaching at night, my kids get very concerned.  I told her I'd call 911 or she would call 911 and then we would call our neighbors to come and look after her and Max.  I told her we were fortunate to live in a neighborhood in which we are surrounded by people or care about us and love us.  I told her that the drs and medicine and I am taking care of me and that she doesn't have to worry about me having a heart attack.  But she said it was scary to think of and I had to agree.  What a crappy, depressing conversation to have to have with my little child.  She said that 4th grade is the worst year she's ever had.  I have to agree.  Boy, do I feel like taking the whole family on a Disney Cruise.
