In her latest programme, Maria spoke to award winning Irish Times journalist and travel writer Rosita Boland.
Rosita, who is the paper's senior features writer, spoke about her book Comrades: A Lifetime Of Friendships. She explained to Maria that the book documents all the friends she's had since childhood. Rosita goes onto say that imaginary friends feature, because she struggled to form friendships in childhood, despite her best efforts.
The book discusses all aspects of friendship in it, and made for a really interesting discussion.
