I've Never Done This Before

I've never had SO much difficulty talking to someone on the phone. So I return this person's call, she asks me why I dont wanna go for this camp coming up.
I give my reason. She replies and replies and replies and replies. I try to emphasize that she has the wrong idea.....no...she continues with the same thing again and again and again...Is she listening? Nope.
As I type this, I've placed the handset on the table next to the laptop (she's still talking) She doesnt even know I've stopped listening. Its been 3 minutes...I'll check the handset. No sound on the other side.
