Thanks Nic. I do now know what was happening but I still have no idea why we were doing it at 2pm!
On closer inspection it seems both bungalows are currently let: I heard snoring from one and rustling from the other. What changed was that both bungalow’s piles of spare straw had gone missing in the previous 24 hours so the commotion in No. 2 Hedgehog Close was a bit of manic nest building.
Why would there be manic nest building at 2 o’clock in the afternoon though? It was 32C at the time so it’s not like we woke up and felt cold! We did sleep through the rest of the day and came out for dinner at about 9pm. All very strange.
