Nevertheless, Rinshi had a jealous side, as can be seen in several places in Murasaki's Diary. While the empress and her attendants were staying at the Tsuchimikado, Rinshi sent Murasaki a great wad of fabric damp with chrysanthemum dew for the purpose of "wiping away old age once and for all"—implying that it would take a lot to erase Murasaki's wrinkles. Murasaki's response was a poem sending the barb straight back to Rinshi—although she had more sense than to actually send it. Later, when Murasaki had taken a leave of absence, Rinshi sent her a note implying that she was staying away out of spite.
Another scene from the Diary describes the boozy carousing during one of the many celebrations following the birth of Prince Atsuhira. Here, Michinaga drunkenly boasts his poetic prowess, and Rinshi rather disgustedly gets up and leaves the room. My sense of her is a lady with a temper that she felt little compunction to smother.
