Congress MP Shashi Tharoor on Sunday said he was not upset or angry with anyone in the Kerala unit of the party and has no reservations in speaking to anyone as "we are not in kindergarten to refrain from talking to each other". Speaking to media in the port city of Kochi, where he came to attend a state-level conclave of the All India Professionals' Congress, the Thiruvananthapuram MP said he has not spoken against anyone in the party or acted against its directives and has no clue why such a controversy has been created.
