I'm not sure if this is romantic to you guys or not, but it means something to me. The last time I saw my girlfriend before I went home for a few weeks I took off the bracelet I was wearing and gave it to her. She was reluctant to take it, but I guess she could consider it romantic that I gave it to her.
Then, the first time she knew she would see me, after getting back from visiting home, she was wearing it. It made me happy :)
