Hey! I enjoyed so much at [place] and it was so much fun spending time with you. I wanted to ask you something but before that I want to know your name again. I know this might be bit weird but I still want to take you out. I am not able to recall your name [reason you can’t remember]. I really feel embarrassed, but I want to tell you, that I am really looking forward to meet you again. I can understand that you think I’m a jerk, but please give me one chance. But I am still hoping that you’ll call. Thanks. Take Care.
