Family and friends pack a lunch, and a dinner, when they join you for a trip to the shopping mall. Today, you are likely to spend a great deal of time at a going out of business sale looking to buy either a half-dozen helium filled balloons or a packet of address labels large enough for addresses of both the sender and the recipient. Be on the lookout for door-to-door salesmen. You should consider shopping at stores or businesses beginning with the letter N, but do not buy any products with a serial number or product code containing the number 617192. Your preferred shopping venue is shopping malls. Your special symbol is the asterisk (*).

You love to compare products and prices. You love the crowds. You love chatting with the store clerks. You love every bit of the buying process. Nothing dissuades you from having a good time shopping, whether you're buying a box of facial tissues or a new house. Does it get any better than spending an afternoon at the shopping mall? No way!
