It was clear that US Secretary of State Hillary Clinton didn't want to be reminded of her 63rd birthday on Tuesday.When Austrian Foreign Minister Michael Spindelegger told a small group of reporters during a Tuesday meeting with Clinton that it was her birthday, she interrupted saying: "Oh dear!"As the diplomats and journalists burst into laughter, Spindelegger said: "25th birthday!"Clinton responded saying: "It coincides with National Austria Day. I'm very excited about that!"There was more laughter — and then both answered questions about another event being marked on Tuesday, the 10th anniversary of the first UN Security Council resolution calling for women to have decision-making positions at every level of peacemaking and peacebuilding.Clinton and Spindelegger addressed the ministerial meeting of the council.
