I think this song is about a relationship between a man and a woman that are not brother and sister, but the Speaker refers to her as "sister" because it's how he sees her now the relationship is over.
The title is "See-Saw", what means the song describes ups and downs, but the song just portrays the "brother's" side. In the beginning the song talks about marigolds, which are flowers very much related to the sun and calendar, what could mean he doesn't cares about other girls, even being on top - his Up.
While he is up, his girlfriend is down, so, her mood makes her do unpleasant thing to him so she can get better. It drives the relationship to an end, and it is a "brother's way to leave" - the most noticeable sentence in the lyrics.
Then, the song goes to the "weeds" and "plastic flowers", what could means she was in bad mood and, therefore, selling her falsity - in the speakers vision - to others in a Sunday, a word, once again, related to the sun, or happiness.
She attracts another man and do to him the same thing she did before to the protagonist, she goes up and he goes down, like a see-saw.
In the end, the speaker repeats the feeling of indifference to love provoked by the see-saw of the relationships, "a brother's way to leave". But he keeps saying "another time, another day", what could mean, at the same time: another person to love him and be loved, or another day that his mood would be warmed by the sun, he would be Up for the price of his beloved one Down.
