- After a while, if not right away, she is going to become very curious as to who her secret admirer is. So, you may have to come clean, especially if you want to have a relationship with her.
- Don't overdo it. One or two letters or gifts (nothing too extravagant either) are more than enough. If you overdo it, rather than being curious the object of your affections is likely to become creeped out.
- Stalking is never good, if she catches you stalking her, you will ruin any relationship that you may have had with her. You might even wind up in jail if you do this frequently.
- Make sure that the reason you're keeping your affections anonymous is because you want to be coy and playful and not because you think she wouldn't be interested. If you think the latter is more likely, then you should under no circumstances attempt to win her over this way. You are probably right, that she wouldn't like you anyway, and you should instead try to become friends with her with the intention of parlaying that into a future relationship.
