Wow, this thread is inspiring. I thought I was the only one who missed so many obvious ones. It's been the story of my life pretty much but I've had it now! I'll only mention a few (there are dozens):
1. Spent the summer in Europe. FIRST NIGHT THERE, it's me, another guy and 6 other girls at this bar/restaurant. The waitress is an 8-8.5. I get up to go to the bathroom and on the way back the waitress smiles at my Jimi Hendrix t-shirt and is like (in broken English) "I wish I was alive when he was...I bet he would've made love like a god." I just look at her blankly and then leave a few minutes later when the other guy (not a partier at all) wanted to leave. WTF. Never got an opportunity like that again while I was there and left the country still a virgin.
2. Had a 7-7.5 back at my place sophomore year. She gave me HER number a few nights before this. So we're watching TV and she's like "when's your roommate coming back?" I said "dunno." She asks me 4 more times. At one point she even gives me a high five and HOLDS ONTO MY HAND AFTERWARDS. She then says she has to go but I walk her back. But that's not the end of this story. A year later we meet up at a party, tells me to call her ANYTIME. She then texts me saying "I meant to give you a kiss. Next time." I wait 4 days to call her and when I finally do, no answer. But that's not all. Then I send her an AFC e-mail apologizing, saying I'm shy etc etc...She then LJBF'ed me. After so much patience, she finally gave up.
3. Camp, one summer. A 7 and really unique-looking girl clearly liked me. We went to the movies as a group and it was her and her counselor who came down the aisle near me and my friends. The counselor was in front but let the girl go first so she could sit next to me. It was an action movie and during the previews she's like "I get scared really easily." Throughout the movie she would start grabbing my arm whenever something "scary" happened. Never held her, never did anything. Finally, she really grabbed at me, too hard actually and I said "ouch!" She then stopped. After the movie I went and started talking to her about the weather. LOL.
4. During HS when I had no friends even...This 8 and me were in the same PE class. We had a flag football unit for a few weeks and I was owning everyone, ruinning the whole length of the field and scoring easily. Afterwards the 8 straight up said "you're hot" and hugged me everytime she saw me. Did nothing.
5. During HS track meet, this girl, she was cute but I don't remember specifics, came up to me smiling asking if I had any cookies. I said nope, she lingered a bit and then left. Afterward, my coach's 11 yr old son who would always come to track meets, who overheard, shook his head and gave me a WTF look. Even he picked up on it before I did!
6. One more. This is depressing me too much. Freshman year of college my roommate had this 9 over. He liked her--one of the few girls that met his ridiculous standards--but apparently she didn't. I met up w/her at a party a wk later and she started flirting w/me, putting her head on my lap etc...The next morning I saw her and brunch and she gave me a huge "hey, NewAndIMproved!" If I even turned around, I barely said hey. No conversation afterward. She tried for about a year but then gave up. Now it's awkward when I see her. Probably thinks I'm gay...or crazy. No one would reject that girl. Oh well.
