It's quite normal for folks to comment in English. Many people get confused with the selection of language as it baffles them whether English is a norm or a language for expression. Yet another reason is difficulty in typing in Devnagari.

While the use of English language in a general term may signify the capability of the speaker when he/she is non native English speaker, a false understanding is on some disdainful chaps that the very use of English is substitute for the strength and the logic of the content. It's a hypocrisy . Don't blame me if I am justifying what I am writing. My oxymoronic displayal, like others, might be the vainful attempt to "glorify"(though that's quite a opposite) my existence in the United States of America (not Africa).
