Do I know you?  please tell me something  about yourself? Are you who I think you are??

Seni tanıyor muyum ? Bana biraz kendinden bahseder misin ? Yoksa üşündüğüm kişi sen misin ?

Exp.Turk.Tut.

 doesnt have to be "düşündüğüm" ?

isnt it supposed to be "düşündüğüm" ?

"D"üşündüğüm

You are right, ReyhanL, it is a small mistake,

Correct one is düşündüğüm

 Niye bu kadar havalanıyorsun ?

 I forgot to tell you that im not english native and also im not Expert English Teacher if i make mistakes in english is normal.

 isnt is spelled isn´t, its short form of is not, you have to use an apostrophe when you drop a letter

 Just like you have to use an apostrophe when you drop a letter in its it´s, because it´s short for ´it is´  ?

 tamam, düzelttiğin için teşekkür ederim

 Düzeltmekten çok dalga geçiyordum açıkçası, ama rica ederim canım

 haha tamam, sorun yok canim

just checking my translation of your sentence,

Düzeltmekten çok dalga geçiyordum açıkçası, ama rica ederim canım = I was obviously kidding about the correction, but you are welcome dear??

İrlandalı

 Almost correct

´More than correcting, I was kidding to be honest, but you are welcome dear´

Good job though

The bigger error is elsewhere;

The translation should read "Yoksa sen dusundugum kisimisin?´" and not "Yoksa dusundugum kisi senmisin?".

There is a subtle difference between the two.

 Another error: the mi-question particle should be written separate from the noun

Yoksa sen düşündüğüm kişi misin?

And I personally would put yoksa at the end

Deli kizin,

The two bold questions above are not identical in meaning. Try translating them both back to English; you will notice ET´s error if you can spot the subtle difference in between.

I know the difference between the two Alpha.

I wasn´t referring to the mistake TT made. I simply said that the question particle is written seperately from the noun. Since the error you refer to is such a subtle one, I was merely surprised that you would spell the question-part wrong. And since this thread seemed to have turned into a ´find the error´-thingy, I couldn´t resist but reply

  Im not expert but i think Alpha is right. Its not "kişi misin" but "kişimi-sin"

 You are not Question particle is always written separate from nouns and verbs:

Çay mı istersin, kahve mi?

Yarın İstanbul´a gidecek misin?

Fotoğraftaki küçük kız sen misin?

Gidiyor muyuz?

But here seems like its not about a question. At least in turkish translation.

 It is Look:

Yoksa sen düşündüğüm kişi misin?

Or, are you  the person I think you are?

Yoksa düşündüğüm kişi sen misin?

Or, is the person I´m thinking of YOU?

I still think its " kişimisin" . But maybe AlphaF will make it clear.

 You might want to check the Spelling Guide (Yazım Kılavuzu) of Türk Dil Kurumu. There it will tell you that question particle ´-mi´ is always written seperataly. Maybe you are confused with ´kişiymişsin´.

Reyhan, Deli_kızın is right.

I am aware of the new rules, yet senior citizens like me gan not get over our century old habbits.  Sorry !

 You are forgiven then  My eye got a bit stuck on the ´century old´ though

I thought it had been a trick in turkish..
