Gave him a scented secret-lover-letter that was partially my own writing and partially a spanish song from shakira LOL!... i was a high school freshman (in my country it reffers to the 10th graders) and he already a high school senior (12th grader).
He didn't even know me at all, but at the end of that school year, a friend of mine told him who i was, and then i faced him! my god! that was really hilarious!, but at that time was one of the most panicking moments of my life, and then a very sweet one because he thanked me and hugged me like a bear, tho he already had a girlfriend and he was just being kind with me, anyway, nothing else happened of course, but it's one of those few good memories i have in my life.
There you have my sweet stupid crush story (i wasn't really in love, but i was a teen so i thought i kinda was haha)
