At Home Depot, I decided to take a rest and sit on one of the garden furniture swings inside one of those netted gazebos, so I pulled my shopping cart close to me so I wouldn't be in anyone's way.  So here comes Mr. and Mrs. Dorkus, who start leaning on my cart, inspecting the gazebo mosquito netting (which they could have done at 3 other places around this structure), then Mrs. Dorkus grabs a garden furniture catalog out of my cart.  I told her, "Hey that's mine, lady," and she looked befuddled which was not surprising.  I commented that the cart also had a box of nails and 2 tomato plants in it, so IT OBVIOUSLY BELONGED TO SOMEBODY.  Apparently I was invisible.  Then these types of people just stare at you, to which I added, "Boy, I'm glad you're not my neighbors."  Could there be any other explanation for messing with someone else's purchases, other than being brain dead or perhaps blotto'd on vodka, or probably both?
