Search Results: blows a kiss

Please read the entire text before polling or answering. Thank you.
Today at 18:30 after school, I walked out of school with my backpack on, wearing dark jeans, white battlescarred shoes, and a metal-band-t-shirt while it was about +6°c. My hair was kinda nice too.
Now the story begins:
I strolled down to the parkinglot with the intention to cross it.
20 meters in front me I saw a group of 8 common, pretty, white, girls walking from said parkinglot. They walked up a long staircase that headed in a direction so that we could see eachothers clearly over the railing.

They were halfway up the staircase and I was walking paralelly away from them and threw a second glance/look at them, just because they were pretty grills.
Then one of the cute girls in the middle of them looked back at me too, like she would've looked at me even if I hadn't looked first. (I'm very good at reading people so I know this is true)
Then she stopped and turned to face me, and gave me a silly nice wave with her left hand while smiling.
I was already smiling before that. I stopped and faced her and waved back at her. It was nice, funny, and silly.
Then she blew me a kiss. I blew one back.
"What's your name!"
"*my name*!"
Something something insignificant I can't remember, but she didn't say anything more.
She waved and continued walking and so did I.

We both smiled at eachothers the whole time, and I didn't notice any of the girls giggling. Could she be attracted to me, did she pity me and wanted to give me some love, or was she just fucking with me? She might pity me because she might have noticed that I'm always alone (but never sad. I'm proud and happy and all that good stuff). She might be fucking with me for amusement. And she might be attracted to me because I am kinda goodlooking. Escecially at a little distance lol ;)

Girls, I would love to hear your honest opinions.
