Angels Must Know...

One of my very favorite memories of Mom was when I was pretty young.  Mom's Christmas decorations were always so beautiful and simple.  She set up the same nativity scene at the foot of our Christmas tree every year.  I don't remember how I did it but I broke one of the angel's wings off.  I felt so bad.  Mom got out the glue and glued it back on while I sat next to her.  After it dried we set it back up.  Sadly, the glue didn't stick and the wing broke off again.  She glued it on and, yes, it later broke off again.  I felt so bad and Mom, instead of getting mad, told me "She must know that angels don't have wings".
