Write a short story with a few English words

It was a very dark night. My phone rang, and then a friend of mine whispered on the phone that he asked me to go to the hospital because his sister caught a cold, but he had too many things to do to accompany her. Then I believed it and rushed to the hospital. I forgot to ask him which room his sister was in, so I waited for a long time, but no one came. After a long time, I received a short message from my friend with only two words: April Fool's Day. I just realized that it was April Fool's Day. Of course, I can't see his sister.
