I have read the ehow.com article twice, in which "develop a sense of humor" has been used six times . And from the profile at the top of the webpage, I infer that the contributor of the article Laura Reynolds is most probably a native speaker.
Then it seems that we need to agree to disagree.
Thank you and all the others who have replied to my posts.
