What does it mean to give your girlfriend a necklace?

Sending a girlfriend is like telling her that you want to tell her on her birthday. I'd rather you stay with him forever, so that he will never forget you, as long as he keeps looking at the necklace and seeing you. This is your eternal friendship. Form of expression. Necklace. Always remember that his play is the most important position on his neck. You will always be in his heart. Best best friend, dearest best friend, you should talk about everything. That's why you gave her a necklace so that she could always see you without you. Do not forget you.
