French people in the backgarden

Our French neighbours knocked on our door and she said "I have dropped my armchair in your backgarden" and I was like "Eeeeh, okey, well, come in..." and we went to our backgarden (and everyone who has seen our backgarden knows how small it is) and I didn't see any armchair, so I asked again, and she said "I dropped my hamster" and I was tired and slighty chocked "hamster? ... hamster?! ... the animal?!" Yes, our French neighbour had dropped her hamster in our backgarden, and yes, she found it.
