Example Input: Person1: Jessica is going back to Holland next week . I've been thinking a lot about what to give her as a parting gift , but I still have no clue .
Person2: is that the girl you spent almost every weekend with ?
Person1: yeah , that's her . We had a lot of wonderful times together . She is really a special friend , and I want to get her something meaningful .
Person2: I am not good at picking gifts . Maybe you can ask if there's anything she needs to make it easier ?
Person1: I don't think so . That way it would lose all the charm . I want it to be a surprise . I want to show her that I care about her and I hope our friendship will last .
Person2: yeah , that's nice .
Person1: hmm , I think I've got an idea . Maybe I can get her an ever-green plant to take back home .
Person2: a plant ? That's creative . I'm sure ever time she waters it she'll think of you . But there is a problem . Do you think it'll be able to go through the customs ?
Person1: I hope so . I'll make sure to get a small one so she can put it into her suitcase . I hope it won't cause her trouble at the border .
Person2: I don't know . I think the idea of a plant going across borders with a friend is really exciting but maybe seeds would be safer . You don't want to get her in trouble .
