My 'I'm really old' moment with regard to Buffy is that when I watch it now I can't help but feel really strongly that Buffy would have had a much happier life if she had stayed with Riley. I was in my early 20s watching s4&5 and I hated Riley with a passion. So much so that I was even gutted in his final episode as her boyfriend that she ran after him. It wasn't good enough for me that he was leaving, I wanted to know that Buffy never really loved him because I didn't think he was worthy of her. Seeing her run after him, just too late, was disappointing (though Xander's declaration of love for Anya was fantastic). But now with 15 years of life experience I can see that he was so much better for her than Angel and Spike and I understand and agree with what Joyce did in The Prom, when I sort of hated her for it for years.
