Singh, who met Congress president Sonia Gandhi on Wednesday, has preferred to keep quiet since the verdict in the Bhopal gas leakage case. Television crews have been camping outside his residence at 17 Akbar Road in New Delhi for the past three days in the hope that he may speak to them on the issue.
Congress sources said that the former chief minister
was not given to impulsive reactions and his move to remain quiet on Anderson's release must be a well-thought decision.
Please explain to me what "was not given to impulsive reasons" mean here?
Though I know "impulsive reaction" means "response/reaction to something without proper thought suddenly". Particularly I'm confused with "was not given to".
