I have learned that if you have a teenager who likes to shop, you must plan on being gone for the entire day.  My daughter wears me out when we go shopping.  She can shop for hours and hours and never feel tired at all.  We went to the mall last week and she bought a lot of cute things and we looked at mod bags.  She looked for what seemed like hours and then finally found what she wanted.  I told her that the next time we go shopping, we are going to set a time limit because her mom cannot keep up with her anymore.
