Actually, initially rivers travel in as straight a line as the surrounding terrain allows but over time begin to curve into more of an "S" shape until eventually they completely fold back on themselves and once again travel in a straight line as a wider river, they can do this repeatedly over a great period of time, which is how we can so easily identify The Amazon River as the oldest existing river in the world because it is the widest.
Rivers never run straight. The faster water runs the more it cuts into the banks. It will eventually create a bend in the river if the water runs faster on one side. Sediment forms where the river runs slower. The process of erosion can change the course of a river over time. Storms help make more drastic changes as the river fills with flood water and overflows it banks. Collapsing banks and sediment deposition can make a river meander from one side to the other. Other factors that help create a meandering course are different forms of bedrock that wear away unevenly, boulders, rockslides and landslides, changes in slope and elevation, spring flooding, differences in the surrounding and underlying soil, etc.

Yes, they do. But they sometimes travel a straight line through bent space.

Part of the border of Queensland and New South Wales is formed by the Macintyre and Dumaresq Rivers, Rivers do not flow in a straight line.
The property of light to travel in a straight line is known as rectilinear propagation. This means that light travels in a straight path until it encounters an obstacle or medium that causes it to change direction.
High pitched sounds, like all other sounds, travel in all directions in waves from their source. The direction they travel in can be affected by obstacles, reflections, and other factors, but they do not travel in a perfectly straight line.
light travels in a straight line because it can only be bend by reflective objects.
