GPS was telling him to go one way, I was telling him the road we needed to get to & his brother was not understanding where we were. He finally got maf, drop the phone on the seat & told me he was really getting to torked off & that if I didn't shoosh I could drive. In VERY plain English I told him where he could stick the gps, his phone & that I would gladly drive because I am the only one that knew where the fark we needed to go grrr.....
