Diccon Chancellor disagrees with the common saying that age brings mellowing, arguing that it is not true for him. He feels that his experience with Mistress Philippa has caused him to age quicker, as he perceives her as becoming less mellow each day. This suggests that his interactions with her are intense or challenging, impacting his sense of aging and patience.
His decision to flee the country indicates that his relationship or situation involving Mistress Philippa has become overwhelming or difficult. Chancellor's words reveal a tension between aging and emotional strain, emphasizing that his time with her has had a significant and possibly stressful effect on him, contrary to the usual belief that aging softens a person.
