Bartender vs. Social Worker

The social worker asked the bartender:

- What's the difference between your job and mine?

The bartender replied:

- I only had to go to bartender school for 6 weeks and I learned to mix very good drinks, then wait a couple of hours to have people tell me their innermost thoughts, while you went to school for 6 years, paid thousands and thousands of dollars, sit session after session using technique after technique, and you still may never hear them!!!
