No one/ can deviate from others in the row.

Perhaps it’s safer just to stay/ indoors than go off course again.

There’s a lot of community pressure in places like this – pressure to behave the same as everyone else and keep your home looking like everyone else’s. I think the lines above can do double duty. “No one” can refer to a bush in a row, and to sailors (as MaryAnn pointed out), but it also can allude to the residents themselves. Anyone with different values and ideas is going to have problems here. As I see it, the narrator is living in this community and knows that her (or his) personality doesn’t quite fit with the others. She might feel she has to keep her mouth shut (“stay indoors”) so as not to risk people gossiping about her or getting irritated.
