My two language affinity   and  my embarrassment : 

It's uncommon and rare for me to interact with someone unless I really need to interact  or they interact with me  and of course when it involves mathematics :) 

But in one of such situations ,mainly when someone asks me "Where are you from?" and I reply "Andhra Pradesh ,Tirupati" and they ask me "so you know Telugu ,Please tell me the exact word for this -- (some random word)".

and at that instant of time(Time of embarrassment T_E)  my whole mind goes blank. I can't get anything related to it. I try to repeat the word several times in my mind, in English,.in Hindi .But even then no use of it. Strangely this happens due to my two language affinity.I would get the exact word for what he had asked in Tamil.

 and this gave me an idea to mathematically think about it.

Let us see my Language set,

L(x) = { Tamil,Telugu,English,Hindi} 

and x_1 - Tamil ,x_2- Telugu and respectively...

So when I speak something (which happens not to often) :
D(t) =  a(t)x_1 ^(x) + b(t)x_2^(y) + c(t)x_3^(z)+d(t)x_4^(w) be my discourse function .

So at t=T_E , b(t) =0

Some other constrains that creep in:

For t=Time at Home(as I speak in Tamil), b(t),c(t),d(t) = 0
As I have studied and wrote x_2(Telugu) , x_3(Hindi),x_4(English) clearly  y>z>w>x.

But finally axioms must hold true

so when I live in my 4-D M Space,

There is no time (the greatest enemy of my life)  .So D(t) = 0

But this is not true as The Axiom of 4-D M Space states that,

" When in 4-D M Space , D= M^(m)  where M is "The Language of Mathematics" and m is unpredictable."
