Hi, Paul Quinn!

    ak>> "What happened to/with you?"   
    ak>> I saw both variants in books. Is there any difference?   
    PQ> There isn't a major difference. Except maybe in terms of context.   
    PQ> The "to" variant might be as a result of some external affliction   
    PQ> pertaining to the person being spoken to. Perhaps an injury? To   
    PQ> which, the usual (joking) response is "you should see the other   
    PQ> guy".   
      
    PQ> OTOH, the "with" query might be that the other person has missed a   
    PQ> meeting, or didn't attend a party. Even then "to" could work.   
      
   For instance, in "An Inspector Calls", by J.B. Prestley:   
   -------------------------   
   Inspector[imperturbable]: Yes. Now what about Mr Birling?   
   MRS BIRLING: He's coming back in a moment. He's just talking to my son,   
   Eric, who seems to be in an excitable silly mood.   
   INSPECTOR: What's matter with him?   
   MRS BIRLING: Eric? Oh -- I'm afraid he may have had rather too much to   
   drink tonight.   
   -------------------------   
      
   Bye, Paul!
