While in college, my roomate came home one day with a Tarot deck and a book on how to interpret it. For fun, he read my Tarot according to the book. I was completely struck with how strongly I wanted to see myself in what he read. For instance: When he said something alone the lines of, "you have had a dark relationship at some time in your past", my mind immediately thought of a certain someone, the fact she had dark hair, and the fact the relationship sucked. But more than just my mind thinking of these things, there seemed to be some emotional desire to think the Tarot was revealing. And, even moreso, all this astonished me because I knew I didn't believe in such things as the Tarot, but was feeling and thinking all this stuff nonetheless.
That experience deeply impressed me with how easy it is to see myself in a Tarot reading.
Naturally, it wasn't long before I happily conceived of a devious and immoral way to exploit this intriguing fact. I bought my own Tarot and book, read the book, and took the deck to the bars with me, dragging my roomate with me.
In the bars, I would sit my suffering roomate down, lay out the colorful cards, and pretend to be reading his Tarot. It often wasn't long before some people became interested in what we were up to. I would then offer to read the Tarot of the women. It turned out to be a great way to meet people!
Nowadays, I think the Tarot is used by some people as a help in contemplating their life, in thinking creatively about their situations, and perhaps even in getting in touch with their unconscious minds.
