Where did you come from?

When our daughter, Emma, is at work we look after her dog, Toby. My husband takes him for his walks, and they usually go to areas where Toby can do a lot of sniffing. One place is a large open space of rough ground, where there are a lot of bushes, brambles and long grass. Since the weather has got warmer this little tree has sprung into blossom, almost from nowhere, and there are no others like it in the area.
