Hello Mr.C.J
Sir, I am a very big fan of you. Your way of explaining is superb. I have got a lot from you and others on this forum.
There is a story in India.
There was a boy who wanted to learn something from a famous guru, but that guru refused to teach him. That guru taught only those who belong to a king family. The boy was very sad. But he had a great respect for that "guru". He admired him because the guru was really a great guru.
The boy came to his home, and made a statue of that "guru" and started learning of the "art" that he wanted to learn from the "guru". Finally he leaned.
There was a competition in which the boy took part and got first. He defeated all those who had got training from the guru.
The guru asked him, from whom you had got training. He said that from you only and told the whole story.

I have never seen you and also can not meet you. But I feel that you are really a very humble man. I don't know how old are you.
But It is sure whatever you are doing, you are master in that.
This is my feeling.
Every time I read about modal verb I get the same word "obligation". Bur really I could not understand the meaning of it.
