You can't always just put color filters in 80s aerobic videos or take stuff from public-access and look at it in this very ironic, self-conscious way. That only takes you so far.
There's nothing better than having an experience now that's the exact same thing I would've done when I was 16, like texting a really awkward "I like you" message to someone. The way you phrase it might change, but it will always continue to happen, and there's something really charming and calming about that.
