When I got the news,I drove home  37  that we just don’t know when a loved one is   38  going to be with us. We sometimes take our loved ones  39 ,and we expect that they will be with us forever. __40 , as we all know, life does not work that  41  and sometimes we get a wake-up call that shocks us and makes us realize how  42  life is.

In comforting her at the funeral, I tried to imagine if I were in her  43   ,how I would feel.

As I was leaving the  44 , I ran into Marilyn, who has been a true friend to me over the years. When she asked me how my job was, I started  45  things through.

She listened to me as I was shouting my  47 , then without saying a word, she took her hands and  48  them on my face, and said to me, “But at least you had a day.”
