How can you tell if someone has a sense of humor?Watch
Of course, there is a lot of difference between having any sense of humour and having a reasonable sense of humour.
see if you can make them laugh. I think everyone here is misinterpreting what a sense of humour is. Like you can test if someone has a sense of smell by whether they can detect smells or not, not whether or not they themselves stink
It's both whether someone understands jokes and whether they are able to make jokes themselves.
ANM clarified 'my jokes'. I have never seen him joke about suicide, so that is not one of his jokes. He never said anything about what he thinks about people getting offended at your jokes.
