A: Why are you bringing a map?
B: I don't want to get lost on our hike.
A: We won't. I have a GPS.
B: There's not always signal in the mountains.
A: Maps aren't as accurate as GPS.
B: We don't always have to use the map.
A: Why bring it, then?
B: Like I said, it's just a safety tool.
A: I think it's just more weight in your backpack.
B: Better safe than sorry.
A: I can't argue with that. Let's get going.
B: Lead the way!
