It’s the one line or few that takes a casual relationship into a true friendship or can turn us into a bunch of animals. The 1st joke usually isn’t spoken before “hello” but should be said before “goodbye” for it can leave a lasting impression to insure that there are more “hello’s” in the future or honestly close the door forever. Some jokes will go over well with the right tribe or at the right time while others will make some go ape. Too many relationships are scared to climb this tree because one step to high can lead one tumbling down as if it was a banana peel especially in the PC times we leave. Yet no strong honest relationship can be true without it. The 1st joke must be said and G-D willing it will lead to many laughs in the future.
