How come you brought "u" in? That's strange.
Basically we have two options:
ai talk ky (exactly the word "talk" in the middle) This one seems to be the most common one.
ai talk ai, ie, "I talk I", which embodies the aim of the site more clearly but few people pronounce so. Yes, in my opinion the 2 "I"s symbol two individuals, one being talking to another.
Hmmmmm!!! I wouldn't answer this question if I knew you were answering it too when I was answering it, Mr Peachey!
