Utterly Mad

Sammy:
Gerald looks at the wound (And nothing else, he swears)
"Well, I don't know much about medicine either. So I guess stopping the blood will have to do..."

You press on the screen of the PDA, and a basic interface of different shapes comes up.

"I guess you've never used a PDA, huh? I don't blame you, they're not easy to find."
He pulls out his own PDA
"You see, with this device you could use a map, write things down, or even directly contact other PDA's if you're in range of the general transmitter."
He swipes on his PDA some times, then push a button saying "accept" that popped up on yours.
"There, you now have a map that should make things a bit easier to navigate with. And I also gave you my adress, you could contact me at any time, or I contact you."
