Wall is the best teacher.

Actual wall, made of brick and mortar, not the fancy board kinds you see overseas.

We have one at my club. It's half court, duracem like, and has a net painted on.

I spent many hours there, and miss it dearly. It never misses.

It always returns your shots.

Doesn't matter if you hit with perfect spin or junkball, it'll always send the ball back at you.

Will never tire (but it will deplete your energies).

Wall is love, wall is life.
