I've been pondering this question all day, and I've had a hard time coming up with an answer. For the most part, I do share the beliefs of my family and friends. If anything, I think I have a bit more of a propensity to think the very best of people. Which isn't always a good thing. It isn't something I do intentionally, so I'm not sure it counts as a belief, but I'm kind of okay with it even if it doesn't always lead to the best results. When Bryce sent me three adorable little cards, one of the things that she wrote in them was that she admired my willingness to be vulnerable to other people and to the world in general. That sentiment kind of took me by surprise, because I'm an extremely private person, but maybe a willingness toward vulnerability comes from refusing to be cynical. So although I don't consider my friends and family to be cynical, let's go ahead and call that my belief.
...and on a completely unrelated note, I made a mug cozy. It's to keep my fingers from getting burned when I'm too impatient to wait for my tea to cool before I take it somewhere.
also, I just thought they were really cute and wanted to make one regardless of whether it served any practical purpose.
