I'm thinking of giving a copy of my own book for secret santa
Is your book not selling well? Is that why you wish to give it away?
I'm trying to make room in my home storage by giving away my books
I understand your situation on wanting to clean your house, but you should be more thoughtful to a Secret Santa. It will come across as selfish and tactless to promote yourself with a gift that the person didn't really ask for.
You are really annoying me. I'm not going to spend a lot of time and money on this, and I just want to get this out of my place.
I'm sorry that you feel annoyed, but it is important to understand that the recipient of this gift will probably see it as self-serving. It's fine to give your book away, but not as a substitute for a real gift that meets another person's true desires.
