Difficult to explain; maybe it's a culture thing, too. Here in Germany, people are still treating seeing a therapist as a taboo. A few years ago, they came up with "coaches" who, from their own webpage descriptions seem to do more or less the same as therapists but do not have the necessary education. So, over the last few years I have heard people talk about having coaching, which seems highly accepted as in taking up personal responsibility for your life and forming it, but therapy still creeps people out (although "everyone" goes).
So, giving this card to a guy would be cheeky and ironic as they would probably take it as a joke (which it is intended to be), yet in my case it'd be simply telling the truth, since I talk to my t about the guys I meet and would like to get more involved in, so I sort of get her approval. Did the other day too and I thought about buying the card.
That's all. Maybe it's just funny for me, but for me it is. ;)
