?Starberry?

Her birthday is next week and I heard she had no friends so I was going to anonymously send her a necklace. And then today I got a letter from her in the mail. It basically said she missed me but she still wasn't completely nice in her letter. So obviously now if I send her the necklace she'll know it's from me. So...I don't know if I should send it anonymously anyway or not send it at all or show up to her house and give it to her anyway or give it to her favorite barista at her favorite Starbucks to give to her or what. I also might run into her on Sunday during this big event we used to go to together and I'm not sure what to do about that either. Help! What should I do about all this?
