So, bit of background, I'm a high school senior. Glad to get away. Graduation in just about a month.

Now, there's a girl, who I've known for a couple years, who last year moved away to a different part of the state. The "Me" she knew is a very different person. A year and a half has mellowed me out greatly, and I have since lost a shitload of weight and have been hitting the gym etcetc.

So, next month she moves back, and I was thinking of using this as my first real attempt at the application of some of the things that I've learned from seddit in the last few months that i've been reading it.

She was never really interested in me before.

Any ideas on how not to fuck this up?

TL;DR girl hasn't seen me in a year and a half, totally different person now, how do I break her preconceptions.
