Thank You guys !
I appreciate you all coming up to this forum and speaking on behalf of me.
Actually I kept myself quiet, thinking whether it would be appropriate to
come forward and say something to Mr.Alex the so called self proclaimed
lingo genius, but then as one of my dear friend rightly put, that I did not
had the time to waste unlike Alex who made his mark by sitting and passing
judgment.
There are more important things to do, while Alex was sitting here making
other believe that others are wrong, me at the other hand managed to secure
clients who were not interested in how i was talking or writing but rather
what I was presenting to them and in what manner.
A good example is to look at Japanese or Chinese. If you wanna do business
with them they do not communicate in written or spoken English.So take the
hint.
And this is for you Mr.Alex next time when you decide to correct some one
please do it discreetly. This is morally and ethically an appropriate way to
do.
