Examples of SLIDING FRICTION is pushing a heavy rock in your path, or moving a box on the floor.
The fact that you can walk without sliding is an example of friction.
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.

Examples of fluid friction are fish swimming through water, an airplane flying through the air and a motorboat skidding over water. Although fluid friction refers to friction through water, it can also apply to air.
