I was listening to that R.E.M. record and was brainsurfing remembering everything that happened that summer.

When you think of one thing that reminds you of another and so forth. Next thing you know, you're thinking of something so incredibly random, you forgot how you got there. Similar to surfing the web.
While brainsurfing, I forgot to call the childhood friend I planned to call, remembering what we used to do together, then ended up wondering what happened to our 5th grade time capsule, and wondering if anyone may have already dug it up.
