You know when somebody says something to you, you don't hear them so they repeat a selection of words from the sentence that make no sense alone?
Example -
DP - have gone to Harry Potter world this weekend?
Me - sorry what?
DP - Harry Potter World?
Me - 
Why would saying Harry Potter World at me make sense in any possible way?
If I didn't hear you I didn't hear the whole thing, therefore you have to repeat the whole thing!
He does this a lot, so does my stepfather, it is really really annoying
If you do this - why? Just why?
