title says it all really - was walking down the street with friend today.
We were chatting, I noticed something he'd like in the window of a shop and turned (we'd walked past) and pointed at it for him to look. He got all huffy saying it was rude to interrupt mid- conversation (it wasn't a big explanation of a concept or anything, just chit chat) and that I'd turned my back on him (as item was now behind us so I turned to point).
I think it's normal to have ebb and flow and interjections in a conversation, particularly if walking down a street. Am I wrong?
