Would this theory be correct?

Alright, so that person who may be interested in me is still something I feel like getting out of the way, and I would not think of putting this into action except for recent events. For some reason she waited for 5 minutes after school, because I was going to pass by a list of moviesI have, but I had said that I would tell her another day, but for some reason, she came up to me in the hallway and told me about it.

Anyways, the theory to finally test if she has some interest or not.

I figure, if someone you like, for some random reason, asks you out, the answer would be yes, and without much period of thought. I mean, logically, why would you say no? Is this correct?

The plan is to ask and see what the response is, then I can mark it off as either missreading her behavior, or mother nature fucking up again and someone else liking me.
