A mirror, or something to reflect light. It can attract attention. Also, when I tip the edge and become completely crazy…I can talk to the person in the mirror! :)
Lighter/matches – something to help me start a fire. I’ve done the rubbing too sticks together – that takes a long time and can be pretty tedious. Give me something that I can reuse! Start a large, but controlled fire to attract attention and to stay warm. It can also help keep some animals away.
A knife. I could cut things down, with a knife, or use it – if necessary, to help defend myself.
I’m assuming I would have a fresh water source on the island, not just salt water. I am hoping for a coconut, or two, as well! demanding for a stranded person!
