A VILLAGER

An old man, who was a villager , was so sad to know that his son was arrested because it was proved that he was a terrorist. He'd been in prison for 2 months.
Oneday he wrote a letter to his son. Here's what he wrote :

" I'm so sad now. You shouldn't of done something stupid. Now see, what good does it do to be a terrorist? Now you're jailed and nobody helps me hoe our field to grow cassava. You see I'm old now. I wish you were here and help me as usual "

A few days later his son received his letter. And next he wrote him back. Here's what he wrote ;
" I'm so sorry, father. But I will always be a terrorist. After I'm free I will do a terror again. Please, don't hoe the field because there I burried so many gernades and guns "
And then he asked a warden for a help to deliver his letter to his father. But then it was sensored .Knowing that he burried gernades and guns in the field, soon the police was sent to the field. They hoe the whole field to find the gernades and guns but they found nothing.
A week later he received another letter from his father saying " Many policemen came to our place last week. They all hoed our our field". What I'm supposed to do now? "
And then he wrote him back saying " That's good , father ! Now you can start growing cassava "
