How do you savor something that's already gone?

There are several things you just enjoy in life, things that made you stick through the less enjoyable part.
Like a good macchiato when you're alone at work at 9 PM.
Or a cute guy sitting at the cafe you normally visit to think about your disastrous relationship.
Or Kanye West's "Stronger" blaring through the CD store as you passed through while on the phone scheduling a meeting.
Or a charming blog that never fails to inspire, even when you feel like a complete moron.

And just like the feeling of noticing the blog's title on the taskbar, cramped between a PowerPoint file, a Word document and a "To Do Today" note, it's extremely comforting to know that you can always resort to several pick-me-ups.
That's why it sucks like hell to have one of them yanked away from you. Sure, it was a hell of a memory, pleasantries and hopeful thoughts were present, I even managed to end it with a bang, but it still really really sucks.
I'm depressed. I know I'll be fine in a day or two, but right now I'm sad and I know there's nothing I can do to stop being sad. It'll pass. I just need to reminisce.
I just got caught in the moment.
I just have to let it out.
I just wish it didn't have to end.
