A: Did you see that puddle of water on the floor?
B: Yes. I called for a clean-up.
A: A puddle of water is very dangerous.
B: It isn't easy to see.
A: But it's real easy to slip on.
B: Especially on these slick floors.
A: Someone who slips could hurt their back.
B: They could even crack their head open.
A: We should stand here till the clean-up person gets here.
B: We can leave if we put an orange cone here.
A: Yes, but I don't know where the orange cones are.
B: It doesn't matter. Here he comes now with the mop.
