Final answer:
Amelie is too nervous to speak with her love interest directly and has a waitress give him a note instead.
Step-by-step explanation:
When Amelie's love interest comes to the cafe, she's too scared to talk to him, so instead she opts for a more indirect approach. Rather than confronting her feelings head-on, she has another waitress give him a note. This action is reflective of her shy and imaginative character, who often resorts to intricate plans and schemes to navigate her social interactions and romantic endeavors.
