Here is Erin Palm's Theory Poem

The number of seashells you have collected is the exact number of relationships you will have. James said he has just three seashells. He has had a total of three relationships. Stacy has seven and is still looking for the perfect shell, which is to say she still hasn't found Mr. Right. Mary has somewhere around twenty--needless to say--she gets around. Todd doesn't collect seashells, which isn't surprising since he still lives in his mother's basement collecting Star Wars figurines. My sister had just one seashell, and she told me she loves putting her ear to it and listening to it all the time. She's happily married to a very talkative man.
