Over the course of a month go looking for other tribes. Before you start searching however, make 3 throwing spears for everyone in the tribe and try to build up a small stock of food so we can use it in the course of diplomacy. Also try to figure out how to make portable tents. Think of it like expanded cloths. You have put things abovve your head and have noticied it keeps the rain away, and you like the animal fur wrapped around your body, so wouldn't it be nice to have animal fur constantly above your head? (just trying to think about how the first guy to come up with the idea of tents thought about it.)
Also, I hope for this entire time we were procreating. We need some more people.
