Context I work next door to the subway I use to work at one day I went in and saw this girl working there and thought that she was cute so I asked for her name and she gave it to me I also asks for her instagram and she gave me that too but when I left her name immediately left my mind later in the day while I was working the manager at the subway came by and I asked him what her name was, he told me and again I forgot I know it starts with a k but thats all I got. Should I just be honest with her and tell her im bad with names and and ask for it again I really don’t know how to go about this
