Question

why did lencho have to write another letter to god​

Answer 1

Lencho had to write another letter to God because he got only 70 pesos (I am not sure about money, u can look for this in textbook) but he wanted 100 pesos from god. When he found 30 pesos less than he thought that the people in the post office are very clever and greedy (but it wasn't true). So he wrote another letter to God asking him the left over money and told god that he mustn't send the money from post.

Answer 2

He wrote a letter again to God because he thought that the post office employees have taken the rest of the money i.e 20 pesos from the 100 pesos..He thought god can never make such a mistake so he again requested him to send the remaining 20 pesos as he is in need of it
