Place the gift and the letter in the bag. Otherwise, leave it under his windshield wiper or in a public place where he'll find it. Now, here's how you write an amazing secret admirer note: Start by writing a short note explaining what kind of gift you are sending and why you're sending it. For example, you could say "I saw you looking at me across the room at the party and thought you might like a present. I bought this book because I knew you would like it." Or "I saw you crying over your broken heart last week and wanted to let you know that everyone makes mistakes but people who love us never stop loving us." Keep the note short and sweet so he won't throw it out after reading it once. Next, write a sentence describing your secret admirer site. Then, link to your site in the space provided. Finally, include your name and phone number in case he has any questions about the gift.
