its difficult sometime to answer

Wasn't very good at studies in school, well that was out of choice but used to get in sticky situations where I didn't used to have answers for my teachers. After schooling was done , I thought this is the end of it, but no then came the bosses. But as I love my work, I usually have answers. But day before yesterday, I got in the situation where I had answer but couldn't give, for not to offend the questioner.

I was supervising repair of our editing machine at my studio, and the man in the question was the engineer, easily 20 kgs over-weight and 4 inches extra and not very suitably fit for this job of his. After figuring out the problem we got on to chatting while testing the machine which required several restarts. So after talking about from where I was, where am I putting up and after g to know that I live alone he asked what I do about my food?

I gave him my routine of my as it hardly changes, usually out of choice as I am trying to control my weight : ! He accepted my breakfast which consists of just milk & mueslli, he didn't asked about the lunch which I usually get at my studio, cooked in-house. But the "?" came on his face when I told him that my dinner is usually 3 boiled eggs

Questioneer : Why?
Me : hmmmmmmm ( i was trying to figure out the question)

Questioneer : You should eat well!
Me : hmmmmmm ( Oh! now I got it, my meal is not up to the usual Indian dinner standard, ever seen an Indian Thali)


















Questioneer : When one is living alone, one should eat well!
Me : Hmmmm (like you?)

Questioner : ? (staring at me for an answer)
Me : hmmmmmm (Well, how to tell him that people should not preach what they don't practice, or understand what does eating well means. This over weighted person who was struggling to get under the editing table, panting after getting up and down couple of times. I don't eat like a that any more as I used to be like that once, 10 kgs and 2 inches more.)

Luckily the system got restarted at that moment or else I had to answer that question for which I had answer, but how to tell an obese that I am happy being "lite" with my boiled eggs.
