X, Y, and Z

X wanted this, but Y wanted that, Z wanted this and that.

This was not what X expected. Perhaps Y was not clear or maybe not completely honest in what Y had in mind. X believed that this comma was meant to be used in a slightly different way, thought that it was inserted into the sentence in order to help organize Y’s thoughts and ideas in an orderly fashion, as was learned in grammar. It looks as if the comma is only adding in another factor (whether Y wants to admit it or not): Z. Upon perusal, it seems that the comma does not help the sentence; rather it makes the sentence a run-on. Perhaps the comma really should be a period, ending the sentence of X and Y and beginning a fresh sentence with the newly added factor, Z, with the correct conjunction this time, of course. After all, in seeing that "Z wanted this and that," it would appear that Z has a better matched compatibility with Y in both wanting "that," while X, on the other hand, only wanted "this." What a shame X couldn't have as much to offer as Z. X always felt more like a constant; maybe that isn't enough anymore. Maybe what Y needs is a real variable.
