These secret admirers are a suspicious group. What are they saying, really? "I love you, but I don't want you to know that I love you."
What do they even gain from this? The recipient of the token of their anonymous love cannot know who their admirer is, and so they cannot know if the feeling is mutual. The Admirer is left in exactly the same place as before, minus a few dollars.
It's as if they want only the part of a relationship where they make the person happy, without any of the other important landmarks: working out disagreements, being a shoulder to cry on...getting introduced?
I wonder if they have group meetings about how secretive they are: Anonymous Anonymous. Unless the rule is that you can't tell anyone about your alter-ego, in which case the meetings would have to be cancelled.
Don't get me wrong, it is nice to be told that you are loved, but it is important to know who loves you. Otherwise it could very well be some creep who has been driving by your house every day at 3:30 because he knows that's when you are outside in the yard, and who has fallen in love with your plant-watering technique.
