Getting away for a short time always seems like a great idea—until you have to pack. 小题1:The rule is: pack light. Here are some tips to help you pack.

1. Make a list. Think of what you need from your head to your toes. 小题2:When you’ve done this once, it’ll be easier next time.

2. Consider buying small-size samples of shampoo, toothpaste, and other items at your local drugstore. You can reuse the plastic containers next time you go away too.

3. Choosing which clothes to bring is probably the hardest packing decision to make. Think once again from head to toe — hat, shirts, jeans, sneakers, etc. Once you’ve picked out what you want to bring, think carefully. Do you really need that extra pair of jeans? If so, fine.小题3:Don’t try to fool yourself. You are the one who will be left holding the bag.

4. Weather is an important factor in your packing. If it’s cold, you could wear a jacket, a - sweater, a regular shirt, and a T-shirt. Putting them on will keep you warm. 小题4:Remember how much easier it will be to carry your bag! As for shoes, you may want to call ahead to see if dress shoes are necessary. If so, one pair will be enough, along with one pair of comfortable shoes.

Remember that it is you who have been invited somewhere, not your things.小题5:So, do it right—pack light.

A.Mixing and matching is a smart and easy way to lighten your load.

B.But packing won’t be a problem if you remember one simple rule.
