I know it sounds like nothing but someone was tapping on my front door at midnight.
I live in a small village, terraced house in small estate. Neighbours all have my mobile no so if one of them were locked out I would expect them to text, and also to call thru the letterbox.
Not a chance it's a friend or family member - they are all at least 20 miles away.
After the first tap (which I initially thought was next door) I went downstairs - thinking it was prob a takeaway for next door or a friend of the 20 something calling to her on the way home from the pub.
But had a look and realised my sliding porch door was open - and I had closed it when I came in round 9pm.
10 mins later they tapped again 4 or 5 times. No way I'm opening the door this time of night! I live on my own (well with 2 cats who are hiding under the bed) so I am just posting till I stop being freaked out and can go asleep. Seems to be all quiet now...
