What do you call it? Innocence or Illiteracy

I met a man on the way from Jalandar to Trichy by Train (Navyug Express). The above mentioned question or confusion is all about him. He boarded at Delhi. His seat was allotted in the compartment next to me. He normally comes to my compartment to seek help to communicate with the server and other peoples he came across because he didn’t know hindi. I too don’t know hindi but my colleague (Aarif) who was with me knows very well. Actually he was the translator.  By the way, the person told the reason for being at Delhi. He is a cook, got job somewhere there. Here are the exact phrases came from him (of course translated) which is the main subject “I was working in Delhi. I cannot withstand the cold there. So I decided to come back again to India”. Hope you got the point. Now tell me what do you call it? Innocence or Illiteracy. What will you do? Laugh or Feel pathetic.
