Long Journey/ Grandparents' house intruder.

I had to drive some people a long way. I went to the car and it was Mila's Range Rover. I drove it for some hours until I arrived at my grandparents house. Then we were transferring to a smaller car. I went inside and discovered that there was an intruder in my grandparents' house. He looked a bit like the new homeless guy who sits outside 'millions of milkshakes' on Santa Monica Boulevard. He wouldn't leave and we decided it was time to call the police. I went to the phone at the bottom of the stairs, my Grandad stood beside me. I paused to think. My grandad wrote 911 on a piece of paper. It confused me and I figured out that I need to call 999 because I was in England.
