Namings?


Tomato, tamato  
potato ,patato
Sub , grinder
Soda, pop
Kroger ,Fred Myers

All the same yet all different?

Why different names for the same thing?

Is whats good for the North not good for the South?

Is whats good for the East not good for the West?

Such weird people all naming the same thing different names.

Can we not all just agree on one name.

So confusing so annoying I must say  its rather confusing to be quiet frank.
