Where did you go

Where did you go

So my friend took a trip to Salem, Ma. I didn't know what for, but I was sure he made a good decision. When he got back, I asked him what he did and he said "I went to a house." I asked him back, "which house?" He replied with yes. "What? I asked you which house!" "Yes, that's where I went." "I don't understand, that's like saying 'oh, where'd you go?' 'To the wherehouse'.
