I wander. My original destination is not completely forgotten, but I end up taking a circuitous route.
My wife complains that when we go anywhere, there's always the chance I'll wander away the moment I see something of interest. If I have my cell phone, it helps her find me. I am at least a creature of habit.
If there are books, movies, music, or food, those are the places to search for me. I can spend hours in a music store and I love bookstores. In a place like Costco, I head right for the "media" tables. I check every stack of movies, CDs, and all the books to see what's new.
Malls are a real problem -- there are so many things to see. Granted, there aren't as many bookstores and music shops are there used to be, but there is a lot of food. Very cool food, too!
Maybe wandering is just who I am...
