I had a new inner front door fitted 3 years ago, solid hardwood with an oval frosted glass panel in the centre. The very next day my daughter, granddaughter (then aged 2) and I arrived at my all-locked-up house, opened the front door and went inside, leaving keys in the house. A passing neighbour called out, as Laura was toddling down the hall, and my daughter and I stopped in the porch to speak to her. Laura slammed the door shut. As the door was new I had not yet passed a spare key to my next-door neighbour so it was a case of smashing the reinforced glass panel to get in. It cost me £75 to get the joiner out that afternoon and a new glass panel put in.
Kids, don't you just love 'em?
