A story

It was evening. I was sitting on a bench under a tree; an opened book was on my knees. I stopped reading for an hour it seemed, because the sunlight was weak. Some noise that sounded unusual broke the chain of my thoughts. It was not an ordinary sound that you hear in a garden or outside. It was like a sigh, but louder and it was not like human breathing. I looked back over my shoulders, wondering, ready to see some animal. But I saw nothing. I don’t remember if it was getting cold or it was a shadow of a fear, but I found myself shivering.

I closed the book and was heading towards home. Suddenly I heard a voice inside my head “Where’re you going? Don’t you want to stay and talk to me”. I was glad that I didn't wet my pants at that moment. Turning around I expected to see the speaker. But there was no one. “You can’t see me, can you?” I heard (or sensed?) the voice talking inside my head. I felt such fear that I had never felt before. “Who are you? Where are you? Show yourself!” I hoarsely said while was looking around for a stupid prankster.
“I’m right in front of you” – said the voice calmly, - “never expected that you human would not be able to see us”.

Hello Sharaf,

This is a nice start to the story, are you going to tell us what happened next?

I have made some corrections but I can understand everything.  When you are asking a tag question, you should use the same auxiliary verb -  remember that modal verbs can act as auxiliary verbs too, can't they? If you are talking about something that happebned before a point in the past when you are telling a story you should use the past perfect - had + past participle. When I got home yesterday I realised that I had left my keys at work.

Hope this helps

Bob
