Conversations with Rugi: Hoop and stick!

One afternoon, Rugi comes into my compound playing that hoop and stick game popular among colonial American children. But whereas colonial children used wooden hoops (made expressly for that purpose?) and a stick, Rugi uses a bare bicycle rim (no spokes) and the palm of her hand. She rolls it into our compound until it stops against the mango tree. “Hup!” And then she turns around and rolls it out. A few minutes later she’s back:
Rugi: Good evening! Binta, I’m going home.
Me: You’re going home?

But she’s already gone.

A few minutes later Rugi returns, still rolling the be-spoked bicycle rim.
Rugi: Good evening!
Neene: Good evening.
Rugi: I’m going home now! Until tomorrow!
Me: Okay!
Rugi: Until later!
Me: Okay!
