The main thing that we needed to worry about was having clothes for the week . Knowing this , we got our suitcases , and made sure to set aside different clothes , including underwear , for just about each day of the next week . Then , we took some extra clothes for swimming just in case we would be doing this while we were over there . After the clothes , we made sure to pack our toiletries , like toothbrushes , toothpaste , shampoo , and so on . The last thing to pack was any other items we wanted to take with us . I decided to take a blanket , and my brother decided to take a pillow . We packed these into the suitcase , and once we were sure we had everything , we went off to our aunt 's house . Question: When did they pack their things? Option1: before staying with the aunt Option2: 4 summers ago
