Bit of an update as i can't remember it i mentioned this, last week or the week before i think we went out for the morning, i came home and did some cleaning while A was at marks aunts, went back and picked her up and when i came home the 2 sliding doors in the lounge room were LOCKED.

The odd thing was when i left i remember shutting the fly screen and NOT the glass door, when i went to open it (expecting it would open) i smacked straight into it! WTF!
Now it was ONLY the two doors to OUTSIDE in the lounge.
DP thinks i'm insane and imaging things!

My theory is that as we don't lock the doors (never have only have a key to the kitchen door) maybe someone was coming near the house, we weren't home and 'the friendly' decided to make sure they couldn't get in.. then forgot to unlock for me to get back in?

So am i going nuts? told DP i want to start locking the doors when we are out, he says don't be stupid BUT some days last week when i was going to get the mail i saw a car at the top of the drive, we live on a mainish road and often people pull over if they are trying to find something etc.
By the time i got to the top of the driveway (on 10 acres) the car had pulled away, a day or so later i noticed what i thought was a similar car in the same spot as i got back near the house, saw it across the paddock and it wasn't there when i checked the mail.
SO DP was home alone on the w/end as i went away, he said at about 11pm he noticed something out the corner of his eye (we have the shutters down on the front of the house), then a car pulled up in the drive with it's lights on the side door (glass sliding), DP thought might be his aunty or something so got up and walked outside and then the car just took off back up the driveway (very long driveway)... WTF?
He didn't see the car etc so when i check the mail and stuff this week will be keeping an eye out....

Am i going insane? Should i start locking the house, we have NEVER had anyone come in here, maybe that person came last time and my 'visitors' kept them out?

Hmmm i think i'm going NUTS! lol
