"It’s much better this way. To have acted it out to show them,although I could not have planned it. " This is an indirect reference to show that Adoja feels that if she doesn't say things in front of her mom and nana because she does not want them to worry about her or laugh at her
" Take Nana. First, I have to struggle to catch her attention. ThenI tell her something I had taken a long time to figure out. And then you know what always happens? She would at once stop whatever she is doing and, mouth open, stare at me for a very long time. " This is an indirect reference to the fact that Nana does not necessarily listen to what Adjoa says.
"As for my mother, she has been speechless as usual." This is a direct inference that Adjoa's mother doesnt say much when it comes to speaking up for Adjoa. Nana is the one who usually makes the comments about Adjoa.
