We all want to be liked.  Even when we don't care about being liked, we appreciate others liking us for not wanting to be liked.

I don't know if Hallmark has a greeting card for such occasions (Thanks for not caring if I like you!) so maybe that is why you have not received such sentiment yet.  Of course, they could always send you a candygram or singing telegram - which in the end would make them like you even more as you care less if they like you or not.

Whatever way appreciation comes to you, you aren't stuck waiting for it.  Appreciation is just a click away.
