<human>: Can you succinctly summarize the text in 1-3 sentences?

Last night I was at a small party with a bunch of friends from my old high school (mostly 18 or 19), and there happened to be 3-4 girls of about 16 there (all of whom go to my old high school). There's one girl that was there that I talked with for hours, and slowly throughout that time I began to devlop feelings for her. I knew of her when I was in school (knew her through chess team) but we were never close. Since last night i've been talking to her on Facebook and texting her and all has been going well, really think I like her and it seems the feeling MAY be mutual, but part of me thinks it's crazy to want to date a girl that's 3 years younger than me and still in Year 11, when I graduated school nearly 2 years ago. 

Any advice here?
