Locked Out

So sitting out on the patio this morning I went to go in and found I had somehow locked the door handle on the back door - all the other doors were locked and I couldn’t believe I was completely locked out. Tried fiddling with a golf club through the cat flap but no dice. So I went across the road to neighbors and they came with a paper clip - still no joy. Then they introduced Nathan, their 2 year old who could climb through the cat flap - unfortunately at 2 it was excruciatingly difficult to get him to understand we wanted him to open the
Deadbolt on the front door - eventually he got it and hey presto - I was back in the house. I have never locked myself out in my life! This was my little hero!
