You're normal, all right!

I've also found that it is absolutely necessary to have a list if I must go shopping. I even try to organize it by each item's location in the store - if I can (This usually requires making the list twice.). I was never a list person before.

Otherwise, I randomly wander up and down each aisle, hoping to accidentally stumble upon whatever I came for in the first place... until the confusion is so overwhelming that I leave empty-handed.

Earplugs and sunglasses - definitely help.
