"Where did you meet last year?"
Translation:Hol találkoztatok tavaly?
Harold, "I can meet with you" would be "Tudok találkozni veled." That's no problem.
I think you misunderstood my comment. If you're a single person, you can meet other people, of course. But you can't just say "I met yesterday", because a single person doesn't make a "meeting". You can only say "I met someone yesterday" or "We met yesterday."
