You can't really throw in humor in your writing unless you're using tons of LOL's and HAHA's and just outrageous sayings. But depending on your hub maybe the person really did think it was funny because it made them laugh, or funny because it humored them, or funny because they're making fun of you!
Just have to take into account again that it's tough to write with emotion. I say you just accept it as being funny funny and move on. Don't let it get the best of you! Happy Hubbing!
