Yea Suzy is a weirdo... Eh hem woops. =) Hehe
But anyway man, I think it was a mistake to tell her so soon that you have a surprise. Can you actually cook? I would have had a few practice rounds and a couple blown kitchens before I tell her to try my dish that I spent hours and hours upon to make it perfect for her.
It's not that easy, I JUST started to cook because I live off campus (away from home). I've cooked three times now, so far so good, my roommates liked it all. Two korean dishes, rather simple though, but not bad for an ignorant male. I'm going to join the cooking club in my college when i get the time =)
If you can cook, I'd recommend her being there so she can visually see you working hard to please her.
