<｜begin▁of▁sentence｜>### Instruction:
As a Dance Therapist who utilizes movement and dance to promote well-being, let's consider a practical application in which we need to merge two dance routines to create a cohesive therapeutic session. Imagine you have choreographed routines with specific movements for two groups - the first group performs from 0 to 10 counts, and the second group performs from 5 to 15 counts. To seamlessly blend these routines, we can use a function similar to BoundingBox.union, designed specifically for merging dance sequences.
### Response:
from some_module import BoundingBox

bbox1 = BoundingBox(0, 0, 10, 10)
bbox2 = BoundingBox(5, 5, 15, 15)
union_bbox = bbox1.union(bbox2)
print(f'Union of bounding boxes: {union_bbox}')
