4.15 Time for tea

I was panicking today - hadn't really got the 366 shot in the bag and then driving along the lane just a mile from home I was admiring the mist lying low in the fields, with the sun low in the sky. It's not easy parking up safely, avoiding cars doing 60mph and spotting gaps through the hedges but it was well worth it to find these guys munching on their tea. Anyone care to guess why tea time is at 4.15?
