Is this coincidence or not?
Just say myself and this guy go to the gym the same time. we know each other years. He knows im always in a certain café on a Friday at 5pm. So we see each other in the gym, then im out walking in a park miles and miles away from my home and we see each other there and smile and exchange a joke. Then on Friday he walks past me in the café and we look at each other and he nods at me.
