How can I moisten my dry sense of humor?
Personally I love dry humor! We all have different types of humor, so don’t try to change yours, please! It would seem unnatural and stilted, so it wouldn’t further your cause. Certain people WILL respond to your humor and that can be the basis of enduring friendships. Perhaps one thing you could do, if you wish to “fit in better”, is to make sure you show appreciation for the humor of others when it tickles your funny bone. You could also try changing your delivery (adopt a comical or exaggerated pose, or change your timbre) so others are sure you are indeed joking — but don’t change the content.
