Vietnamese Tradition

A soldier in Vietnam saw a local man coming down the road with his wife
behind him with a bicycle loaded with all their worldly possessions. The soldier
asked him why he carried nothing but a cigarette and his wife had to push the
bicycle alone. The man replied, "TRADITION".
Two weeks later he saw the same local man on the same road but this time she
was in front and he was pushing the loaded bicycle. The soldier asked him what
happened to TRADITION and the man said "LAND MINES"
