I ask her where she needs to go, and she tells me she wants to visit some relatives, but isn't sure about their address. So, I took her home so she could check our phonebook.
- Once there, I saw her dress is pretty ragged, so I decided to give her your old dress. Nearly two years that it's been hanging in the closet, and you never wore it.
- Then, I saw her shoes are also about to fall apart, so I gave her your old shoes, which have been doing nothing but collecting dust for three years. Of course, she said thanks, and then asked:
