A friend in need is a friend indeed. En las malas se conocen a los amigos. A man may learn with every day. All talk and no action. Mucho ruido y pocas nueces.
Cowards die many times.
Beggars can't be choosers. Cuando hay hambre, no hay pan duro. Different strokes for different folks. Sobre gustos, no hay nada escrito As sure as eggs is eggs. De tal palo, tal astilla.
