I will lead by example:
As for who I appreciate, this very special person I am appreciating doesn't even need a hint to know that they are the one. Because I tell this poster all the time. But I wanted my favorite to know in public. And this poster will know.

I expect no discrete appreciation in return, or from anyone else, I just wanted to really get my feelings out. But if anyone wants to just throw something out for self-indulgence, that will be fine. Just remember, "discrete".
