Actually, Tyrannosaurus invades us all time, we are moving to a safe place away from them, which is the forest.
But, if I go to the Tyrannosaurus and made them chase me all the way to the forest, we might run away and move to another safe place far from you and your friends.
Though, this might fail, as Tyrannosaurus are faster, I might got killed. But its worth the risk. >.>
