Šta kažeš posle zdravo (What Do You Say After You Say Hello) by Eric Berne is a foundational text in Transactional Analysis that explores how childhood-decided "life scripts" dictate behavior patterns and personal, professional, or social outcomes. The book is considered an insightful yet dense, semi-academic read that, despite its 1970s origin, provides enduring insights into psychological "games" and parental "injunctions" that shape adult life. It is commonly available on academic sharing platforms and regional digital libraries.

First, "Erik Bernsta" is likely a misspelling of "Erik Bernhard Bergsten," but more probably "Erik Berna" or "Erik Bernst" is correct. Maybe they're referring to a book or a document. The words "kazes posle zdravo" in Serbian/Croatian/Bosnian would be something like "say hello after" or "you say hello after." "PDF" is straightforward, so they want a text or document in PDF format related to this.

"Zdravo," Marko said automatically.

His first bestseller, Games People Play (1964), became a global phenomenon. It dissected the hidden "games" (e.g., "Why Don't You – Yes But," "Now I've Got You, You Son of a Bitch") that dominate social interactions. But Berne felt he hadn't gone deep enough. Games People Play described the what and how. What Do You Say After You Say Hello? describes the why.
