If your friend is tanning by the poolside looking into the water how would you swim toward your friend under water to avoid being seen?

To swim toward your friend without being seen, I would first take a deep breath and submerge myself underwater. Then, I would glide quietly and smoothly, using a freestyle stroke while keeping my body low to minimize visibility. I would also stay close to the pool's bottom and use the water's natural refraction to help conceal my movement. Finally, I'd emerge a few feet away from my friend to surprise them, making sure to stay stealthy throughout!
