<human>: Give me a shortened version of the text

We're two completely different individuals (I am 26, he is 28. both males) but he cannot accept who I am so he left me a Facebook message saying, "You are sad." and blocked me. What caused it? I told him the character I most relate to in American Horror Story was Dandy as a joke and laughed about it. 

He told me "You overthink things." I asked him to explain, he replies, "Oh, dear lord." followed by "You are sad."
The gifts were from Etsy and can't be returned.
Any ideas what I could put inside the card? I don't want to fight. I think if friends can't figure stuff out together, then it's not meant to be.

I was thinking, "Happy Holidays, Sincerely, Sad [My Name]" with a sad face.
I am sad. Having been friends with him for over 6 years with a few arguments along the way because of how different from one another we are.

Thank you, Reddit.
<bot>: Friend wants to ends relationship and blocks me on FB. Already bought him special card that can't be returned. What do I write in it?
