How was the knight’s son, the squire, different from his father? he was more interested in courtly love. he had no interest in battles or fighting. he did not want to go on the pilgrimage. he did not display the characteristics of knighthood.

I believe that the Squire was more interested in courtly love.
He is a noble warrior, having participated in many battles, but the reason why he fought wasn't for a good and noble cause, but rather to attract more women. He is interested in being around many women all the time and having a good time.
