Can someone translate this one sentence for me?

Sana karsi tatli olamiyorum.

Thank you very much!

 I can´t be cute/sweet to you.

that sentence doesnt make much sense in turkish.

i know also.

 Why not?

It has been writting by a Turk.

 Just because it is written by a turk , does not mean it makes sence. Some turks like in all nationalities do not know their own basic langauge and some do not know the meaning of puncuation marks.

maybe it makes more sense

I cant be sweet for/towards you

just an idea

as a native speaker, handsome, single turkish man it makes sense to me.. and it would make sense if i were not that handsom too.. we use phrases like this all the time.. such as;

sana karþý tatlý olamýyorum.

sana kýzamýyorum.

ona karþý anlayýþlý olamýyorum.

of course it wont make sense if you cant be "sweet" at all..

as a native turkish speaker i have never heard "sana karþý tatlý olamýyorum" in my life

Over two years ago - not long after I joined TC - I asked a Turkish guy what the word ´muthiþ´ meant.  He told me he had never heard the word in his life!!  I think I must hear that word 20 times a day on TV now I live in Turkey - so it´s obviously not that unusual!! 

Is it likely that everyone knows every word and expression in their own language?  I´m sure there are expressions and sayings that not everyone knows - maybe depending on whereabouts they are from?  I know in the UK a lot of expressions used in the North of England for example mean absolutely nothing to us southerners!!    Even at my advanced age I often come across words or expressions I have never heard before
