This is has happened twice, the most recent was Friday 27th of April 07 this year... But the first time happened last month. I'm usually home alone (since I dropped out of school), I took my dog outside for him to do his business and I was listening to my ipod. The song I was listening to had just stopped and I heard my front door open and close... My dog heard it to because he started barking, I thought "oh it's mum or dad", so I thought nothing of it, but because I hadn't done my chores, I realized if it was mum, I'm dead, if it's dad I'm still safe... So I walked through the garage to the front to see who it was by seeing the car and to my shock NO CAR! Which means somebody had entered my house! But both doors were supposed to be locked! I grabbed the rake from the garage and entered the house in the back way, I said loud and clearly "I know you're here, come out" I continued saying that while checking the house. I went to the front and the front door was open and the fly screen was shut... But both doors were shut and locked before! I continued to check the house, nothing was there, I know somebody/something was there because my dog started barking and I heard somebody come in!
The most recent one, as before, I'm home alone but this time I was in the house on my laptop on the other side of the house, I heard the fly screen and front door open, and then I heard a thud on the kitchen bench, like mum's bag usually does so I thought, oh mum is home! I wanted to show her something that I made on the laptop, so I walked through and nobody was there... Not even mum's bag! I walked to the front door and the front door was open and fly screen was shut... I grabbed the first item I saw which was an umbrella and checked all the rooms... Nobody was there.
