<human>: Basic facts, female, 15. So, in March of last year I traveled to England with my class. While there I got hit by a very nice young man in a museum. Now, I don't consider myself a pretty thing, let alone someone who could get hit on by anyone, so this was a huge burst of confidence. I told all of girlfriends, we talked about it for days, even went back to the museum with the hope of seeing him. It was a big deal. 

And about ten minutes ago my friend brought this boy up again. I was bored and amused by the thought of him (I still get butterflies thinking about it, good and bad). So I searched his name and the name of the museum he worked at on facebook.

I found him. Almost a year later and I found him. 

Yes, he is older. He is 19 by my math (he never told me when I met him). But I am 5'9 and have looked 18 since I was 11.

I don't think it would appropriate to pursue anything with him, but I just want to say hi.

My thought was that I could set up an anonymous facebook account, introduce myself and basically tell him that what he did (even if it was a dare or a joke on his part) has boosted my self confidence so much etc. (I do plan on telling him my real age, and how creepy I am). Basically, closure.

I just want to know from the perspective of some older people who are not my parents, if they think this a good idea.

Give me a shortened version of the text
