This type of friction is called lubricated friction. Lubricated friction is a type of fluid friction where a fluid separates two solid surfaces.
because of friction
Normally you can't stop friction alltogether, but water can certainly reduce friction considerably. Did you ever slip on a wet floor? This is because the friction is much less than usual.
If you were roller-skating you don't need friction because it slows you down. Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction). If you are ice skating you do not want friction between the blade of your skates and the ice.
Without friction, your feet would just slip right off.
yes friction is very useful because it help objects not to slide or slip
because of friction
So you have good grip on the floor and do not slip!
You lose balance, then with the help of friction, you glide across the floor. There also may be an injury
because the water reduces friction between the surface you are standing on, and your feet.

No friction is not always bad. In fact consider an example of running on wet floor. If there is too little friction it might cause you to slip and slide.

I read that people slip on ice because of the interplay between static and kinetic friction, I hope this helps : )

The puddle changes the coefficient of friction of the floor. Therefore it becomes more slippery.There are ways to control or change the COF of a floor surface with specialized floor treatments which will make the area much more safe and prevent slip and falls.
an object would slip and slid
lack of friction?
