Thank you for your response. It's greatly appreciated.

I really don't know how to exchange numbers in front of teachers without it seeming to be conspicuous. Especially in front of the teacher I'm studying with. That is why I was thinking of getting her number from her daughter--is there even an inconspicuous way to do this? If I wasn't in front of other teachers constantly this wouldn't be an issue. Is there a non-stalker way to go about this without involving the gossipy teachers around us?

But actually I also found her phone number from this art website (I didn't pay for it, it was public domain), but obviously it would be weird and kinda stalkerish to text her from here I think...

We did both have cancer, so maybe I can invite her to coffee to talk about that and go from there?

The daughter invite thing happened and when she suggested it I immediately said yes, because I was awestruck and didn't know how to respond. Is there a way to backtrack myself out of this? Was this bad that I did this?
