An uncanny story

When I was a child I used to live in the family’s country house all my summer’s holidays. Very often I felt unhappy because I was away from home and I missed my family, especially my mum. That means I was homesick. In fact, I hadn’t any reasons for feeling bad because my grandmother and my aunt made me feel comfortable at home by doing all that I wanted and even buying me all I asked for. Although I was only nine, I can remember perfectly how they pampered me all the time. My cousins made fun of me about my sadness, specially, my cousin Maria used to tell me scary stories and silly tales in order to make me laugh.
One day, we were sitting down on a bench opposite the house, the sun was going down and there were wonderful colours and lights in the sky when several insects began to fly around us. Suddenly, we saw a humble-bee and Maria said: “you are lucky because this humble-bee is brown and a good thing will soon happen. But take care when you see a black humble-bee because then a bad thing will happen”. Although her words sounded as a joke I paid attention to her and I thought: “I wish my parents come soon!”
It was no longer than past eleven when I went to my room to sleep. Suddenly I heard a car. It stopped in front of the hause and after a while I could hear my mum’s voice. I jumped out of my bed and I run to give her a great big hug.
Some days after, in the evening, we were playing in front of the house again when I saw a black humble-bee flying around the light. I felt very bad and I was afraid for my family. After dinner my aunt was on the phone for a long time and when she finished she told me that my mum was in the hospital because she had had an accident.
Was it a coincidence or do you believe that some kind of animals can announce you positive or negative events?
