There is someone that I met in the grocery a few months ago and I felt like I knew him from somewhere but did not know who he is and where I recognized him, so I went over to him and asked him who he is and were I know him from, he responded that he was wondering the same about me
Anyhow I met him again tonight in the grocery and he asks me again "so who are you? "
I told him that we came already to conclusion that we know each other from somewhere and we don't know where
