2. The right kind of gift has never failed to impress anyone. Take time and find out her likes and dislikes. Buy her a small gift and along with a note, place it outside her doorstep. If you already know the girl, you can write about your feelings in detail. If not, just a sentence on what you feel for her, along with your contact details should suffice. Again, wait for a few days for her to get back. If it doesn't work, move to step three.
