the mall

How come when ever I walk into the mall to buy something I end up buying so many other things. This time I was with my mom so I wasn't wandering off too much in the wrong direction. However, instead of the matching skirt I wanted for my top, I ended up buying myself a skirt which I think will match to the turquoise T-shirt I have ... but what should I do about the top that still doesn't have a skirt? I wonder how many more skirts and tops I have to buy before I can find a matching skirt for that ...
