She asked if I'd had any other household projects lately.
What projects are you referring to?
It's for my students to try and sell at the school fair
It seems like she is just trying to be involved. It is good that she is showing interest. It means that she actually cares.
Yeah I think you're right, she does actually show some interest.
When she's trying to find out more things that are going on your life, but definitely shows she is interested. I would recommend continuing to be open with her.
