Interesting how people have put graduations, weddings, etc.
-cheesy alert-
For me the best days were those I'd just spent time with people I really loved and cared about, after a day someone made me think differently, challenged myself in ways I hadn't before, seen someone in a completely different light, held onto a major secret someone had just told me.
This seems weird, but it seems the relatively uneventful but satisfying days were the best ones.
