I was going to say Rosie comes by it honestly, but someone beat me to it.Originally Posted by Rosiemac
I'd speak, it wouldn't be me if i didn't
I would definitely say hi - I've been known to start up conversations with strangers on the streets of downtown Toronto. My brother was visiting from Missouri and we were doing the tourist thing in Toronto. I was walking along talking to this man and after we parted ways, my brother said it was amazing that you could meet someone you know in such a big city. I told him I never met the man before and my bro was astounded. But then a bus stopped in front of the hotel where we were and my neighbour's mom got off (she was on a senior's day trip) so we chatted a bit and my bro really couldn't believe that one.
So yes, I would definitely say hello.
