Actually the answer is all they need to do is let go of one hand so then they will make more room for themselves. Whenever we are in a vulnerable situation we become tense and do not know what to do or we just try and fight back. This is wrong. We need to relax, and keep our distance, so we should step back. To do this the solution is to let go of one hand.
