Michael often shared Shakespeare's Sonnet 116:
Let me not to the marriage of true minds.. Admit impediments.. O no, it is an ever-fixed mark that looks on tempests and is never shaken.. Love alters not with his brief hours and weeks.. But bears it out even to the edge of doom.. If this be error.. I never write, nor no man ever loved
