Problems of the Young Urban Male

My current apartment is close, I mean incredibly close, to a well stocked grocery store. As such, I rarely keep very much food in my apartment, but rather buy things as I need them. As a result, I find myself spending, comparably, an incredible amount of time in the grocery store. So much actually, I've abandoned my old ways of having a list to shop with, I feel like such a pro, I just wing it now. Quite often however, once through the turnstile (I never grab a cart or basket, to discourage compulsively buying more than I can carry), I realize I have no idea what I'm looking for.
Panic typically sets in after I've done 2-3 laps around the store, somewhere between bread and dairy. You see, a grocery store isn't like say, a clothing store, or a gun store, where you can browse with the option of not buying. If you're in there, you're buying something, the only way out is through the cashier.
"Eff sake," I say to myself, "People are staring. Just pick something up for Christ sake." So I go to my safety item, milk. Immediately after, I feel better. Even though I still have no idea what to buy, no one thinks I'm crazy for wandering back and forth all over the store, they just think I'm trying to find something to go with my milk.
