Four college-aged individuals- two males and two females- sitting on the concrete steps outside of a brick building
The students are sitting outside waiting for their professor, who is late.
College-aged individuals don't have to be students. Just because college-aged individuals are sitting outside a building doesn't mean they are waiting for their professor who is late.
