I walked up to her in front of the entire school, and flat out asked her to go to the school dance at the end of the year with me. She was the prettiest, most popular girl in school, and she'd flirted with me and chased after me hard for close to a year -- in fact, she'd already asked me out about 6 months earlier I'd been too scared to say "yes". But by the time I finally asked her out, she'd largely given up on me -- the window had passed , and she'd moved on. I didn't know about escalation windows at the time, though I guessed something like that might be the case -- and sure enough, she said "no," albeit in a very socially gracious way. She told me she wanted "to be friends first," which I knew meant we weren't going to the dance together.
