Being locked in like that would have been my worst nightmare!
I have been locked out - in a hurry to get to the airport to meet my mum, I started to panic when my now ex husband hadn't turned up to take me and my son. Thank fully, my friend's very kind husband had offered (ex and I were splitting up and mum was coming over to help me pack up to return to the UK) so I had to go across the road to ask if he could take me after all. Grabbed what I thought was everything before getting in his car - then realised my house keys were still on the hall table!
My friend's daughter's boyfriend said that it would be no problem - he'd locked himself out a few times, I had left the kitchen window open a tiny bit, so we left him to it.
Got back, and he had managed to open the window and climb over the draining board and sink to get in the house, pick up the keys and take them to my friends - before that, he mended the catch on the window , as well as a kitchen cupboard door that wouldn't shut properly and the hole in the back screen door!
Found out some time later that he had admitted to his then girlfriend that he hadn't been locked out, he'd actually been in juvenile detention in his early teens for burglary!!!!
