Past Diving

Spending time going through sentimental items or messages in order to feel what you felt when you first received them. This is easily done through Facebook and Myspace, but can include going through messages/posts/comments on other social networking sites, emails, or old items in drawers in your room (e.g., that letter that your ex-boyfriend wrote you six years ago in which he swore he'd never leave you, although everyone and their mom knew he one day would).
