This is crazy
Of course it is, and I bet the real cave days were crazier. Sometimes the hunters never get back home, likewise those who take refuge in a cave, both are neither safe nor protected, but it is what it is.
More reason the cave life isnt nice at all and humans have to ditch that to find a safe space which is getting even more dangerous on a daily.
Life has to move on, weather the hunter gets back or not, or if his cave girl gets eaten by a bear or not.
