I like your list, many I engage in and alone too
I agree with this post you just posted, many things can be done alone, and about having someone you love that doesn't reciprocate, I personally would want to be alone.
Like the things on the list, especially playing with a pup, I give my 8 year old dog hugs and kisses and it makes me feel content, even if we nap together, ha!ha!
