Well to be honest I wouldn't forget but if I did I would immediately remember it's better to have a working relationship with one person then have two and in the end have it blow up in my face like a previous rocket experiment of mine.
Educational pointer of the thread: Kno3 exhaust flame will burn you but doesn't actually hurt a lot.
is this something like the movie 50 first dates? well if i forgot i would have the person constantly remind me like adam sandler did in the movie [like a daily showing off the recording of the wedding and such]
