Things that happened in the night; no. 7

My grandmother had a summer cottage.  I loved to be there with her partly because I had a friend next door with a welcoming family.  One July night when I was 10 my grandmother died from a stroke.  I was the only one staying with her at the time.  It's hard to explain how I knew she was dead but didn't, saw but can't yet see what happened.  I waited from dawn by a tree on our front lawn until my friend was ready to go swimming.  And maybe Grannie would get up soon too.  My father arrived at dinnertime to take me home.
